May 2013 Climate And Weather Review For South Central Nebraska
And Portions Of North Central Kansas

...Near-Normal Temperatures...With Above Normal Precipitation Focused Primarily In the Northeast Half of The Area...

The following narrative focuses on climate and weather highlights for the month of May 2013 across the NWS Hastings coverage area, encompassing 24 counties in south central and central Nebraska, and 6 counties in north central Kansas. Click HERE for a map of this coverage area. The temperature and precipitation data presented here are largely based on the NWS Cooperative Observer network, along with data from a handful of automated airport sites. All climate averages and "normals" presented here are based on the official NCDC 1981-2010 normals.

- TEMPERATURES....(According to 30-year averages, "normal" May high temperatures in South Central Nebraska gradually climb from the upper 60s early in the month to the upper 70s by month's end. In North Central Kansas, highs gradually warm from the low 70s to near 80. Low temperatures across the area generally climb from the low or mid-40s early in the month to the mid-50s by month's end...)

For May as a whole, monthly mean temperatures (resulting from averaging together the daily highs and lows)  were fairly unremarkable across the NWS Hastings coverage area, with essentially all places ending up within 2° above or below normal. In general, the western half of the area (generally west of Highway 281) favored the slightly above normal regime, while eastern counties tended to fall slightly below normal. However, what many folks might remember best about May 2013 was the very chilly start to the month...cold enough to support measurable snow in many places on the 1st (see precipitation section below for more details). At locations such as Grand Island and Hastings, where temperature trends were generally representative of the 30-county area as a whole, each of the first six days of the month were solidly below normal, with the 1st-4th averaging anywhere from 11-16° below normal with high temperatures only between the upper-40s and mid-50s. In the wake of the early-month chill, temperatures stabilized to near normal values for several days, before peaking with a dramatic, one-day blast of heat on the 14th. On that day, readings across most all of the 30-county area soared to between 95-103°, including 102° at Grand Island. Not only was this the 3rd-hottest May temperature on record in Grand Island, but more significantly, was the earliest 100+ degree temperature on record during any year, besting the previous mark of May 20, 1925, by six days! Already by the 15th, a passing cold front dropped temperatures back to more seasonal levels, although above normal temperatures persisted for several more days. Following a brief cool-down with highs only in the 60s in most Nebraska counties from the 21st-23rd, temperatures across the area during the final week of the month averaged very close to normal. At Hastings airport, 15 of the month's 31 days featured an above normal mean temperature, 13 days were below normal, and three days tied the daily normal. As for daily low temperatures, nearly all locations notched their coldest readings on the 3rd, with lows generally between 25-32°. For much of the area, this marked the last sub-freezing temperatures of the spring. 

Per NWS cooperative observers and a few automated airport sites across the 30-county area, some of the hottest readings of the month (all occurred on the 14th) were 103° at Edison and also two miles west of Genoa, and 102° at the Grand Island, Aurora and York airports. Several places attained 101° that day, including Osceola, Beaver City and Ravenna. Some of the coldest low temperatures of the month (mainly occurred on the 3rd) included 21° at Webster Dam KS, 22° at Beaver City and 23° at Holdrege and Red Cloud. In the Nebraska Tri-Cities, Grand Island airport claimed the hottest reading of the month with 102° on the 14th, while Hastings and Kearney airports tied for the coldest low with 28° on the 3rd.

- PRECIPITATION/SNOWFALL/FLOODING
...(According to 30-year averages, "normal" May rainfall is between 3.75 and 4.25 inches across roughly the western half of the NWS Hastings coverage area (generally west of Highway 281) and between 4.25 and 4.75 inches for locations east of the Highway 281...)

For much of the area, May averaged fairly dry through the first 3+ weeks of the month, before multiple rounds of thunderstorms dumped a few to several inches of much-needed precipitation mainly between the 24th-30th. However, not all places benefited from this late-month rainfall (which mainly targeted the northeast 1/2 of the coverage area), and as a result several southwestern counties finished below normal for the month. Snowfall-wise, a rare, measurable May snow up to 2 inches occurred in some areas primarily on the 1st. For places such as Grand Island, this was the first May measurable snow in 46 years!

Based on reports from around 65 NWS Cooperative Observers and a few automated airport gauges, and also incorporating radar-derived estimation, it was a fairly even-split within the 30-county area between above and below normal monthly rainfall, with roughly 53% measuring above normal, and roughly 47% below normal. Breaking down the extremes a bit farther, roughly one-fourth of the area reported at least 150% of normal May rainfall, while in contrast roughly 15% of the area observed no more than half of normal May rainfall. Geographically, the breakpoint between the above and below normal regimes was roughly a northeast/southwest split. In general, the majority of below normal totals concentrated southwest of a line from roughly Lexington-Minden-Nelson Nebraska...and including much of North Central Kansas. In turn, the majority of above normal precipitation concentrated northeast of this aforementioned line, including the Tri Cities area. Fortunately, even within the below normal areas, nearly all places measured at least 1.50" for the month. Per a combination of NWS cooperative observers and NeRAIN observers, several of the highest known May precipitation totals included 9.83" seven miles southeast of Stromsburg, 9.20" three miles northeast of Shelby, 8.73" six miles southwest of Columbus, 8.49" four miles west-northwest of Alexandria and 8.33" at Hampton. At Grand Island, the 6.77" monthly total resulted in the 15th-wettest May on record dating to 1896. More remarkably, the 24-hour total of 3.09" that fell from the 24th-25th was more than ALL cumulative rain that fell during the four-month period between June-September 2012 (2.84")! On the drier side of the spectrum, those areas that received less than 2.50" during the month were largely concentrated in southwestern counties such as Phillips, Furnas, Gosper, Harlan and Phelps. A few of the driest sites from these areas were Logan KS (1.51"), Cambridge (1.57"), Phillipsburg KS (1.59"), Edison (1.77") and eight miles south of Elwood (1.91").  In between these wettest and driest extremes, much of the 30-county area reported May precipitation totals somewhere between 2.50" and 6.50", including stations in or near Hastings, Ord, Ravenna, Wolbach, Minden, Cozad, Beloit KS and Smith Center KS.  Among the Nebraska Tri-Cities airport sites, Grand Island was the May precipitation "winner" with 6.77", followed by Kearney (6.54") and then Hastings (5.67"). 

Although localized/short-term lowland and agricultural flooding affected several, primarily eastern counties at times during the last several days of the month, widespread, substantial flooding including on larger streams and rivers was not an issue. This was likely a function of soil being able to absorb a considerable amount of water given the ongoing large-scale drought during the past year, and also a shorter-term dry spell that defined much of the first 2-3 weeks of May.

Snowfall-wise...the month got off to an unusual and very cold start, with many areas reporting light accumulations up to around 1" that primarily fell on the 1st. A handful of sites measured even higher totals up to 2", including two miles west of Genoa (2"), Greeley (2"), four miles north of Aurora (1.5"), Belgrade (1.5") and Central City (1.5"). For places such as Grand Island (0.7"), this was the first measurable May snowfall since 1967...46 years ago! 

(Please look farther down the page for much more information on May 2013 precipitation and extremes, including rankings of wettest and driest locations, percent-of-normal plots, and a detailed breakdown for Grand Island, Hastings, Kearney and Ord. In addition, the link on the far upper right of this page contains an archive of monthly precipitation amounts for around 65 locations.)



- DROUGHT STATUS...Thanks to above normal rainfall across primarily the northeast 1/2 of the 30-county area, a decent percentage of the NWS Hastings coverage area realized a one-category improvement in official drought classification from the U.S. Drought Monitor over the course of the month, marking the second-consecutive month of improving conditions. In contrast, several southwestern counties that measured below normal May rainfall essentially maintained status quo. Per the May 28, 2013, Drought Monitor issuance, most locations northeast of a line from Grand Island-Hebron Nebraska, along with parts of Jewell and Mitchell counties in Kansas, had improved to D1 Moderate drought. In fact, a small sliver of eastern Mitchell County KS was indicated to be free of drought conditions, although still assigned category D0 abnormally dry. This marked the first time since early-July 2012 that any portion of the NWS Hastings coverage area featured something "better" than D1 drought.  The news was not as positive in the drier southwestern areas, where most counties located both south of Interstate 80 and west of Highway 281, including Rooks and Phillips counties in Kansas, remained in D3 extreme drought, with even small portions of Furnas, Rooks and Phillips counties still in D4 Exceptional drought (the worst-possible category). In between the aforementioned extremes, several counties such as Valley, Greeley, Sherman, Adams, Webster and Nuckolls ended the month in D2 severe drought. Looking beyond the borders of the 30-county NWS Hastings coverage area, notable improvements occurred across Kansas and especially Nebraska as a whole. As of May 28th, around 39% of Nebraska and 48% of Kansas was assigned Extreme or Exceptional Drought (versus 77% and 57%, respectively, back on April 30th).

Despite the positive precipitation trends for much of the area during the past few months, there is still plenty of room for improvement to fully relieve drought conditions across South Central Nebraska and North Central Kansas, as notable subsoil moisture and groundwater deficits still linger from the intense dryness that marked most of summer-fall 2012.



- SEVERE THUNDERSTORMS/HIGH WINDS...Other than localized large hail in North Central Kansas on the evening of May 8th, the first half of the month was very quiet severe-weather wise. Needless to say, that trend changed in a major way during the latter half of the month, as fairly significant, widespread severe weather events unfolded on the 19th, 27th and 29th. On these three days, a cumulative preliminary total of 13 tornadoes occurred within the area. Per damage surveys, the two strongest tornadoes occurred on the evening of the 27th, consisting of a large EF-3 that tracked just north of Lebanon and Esbon KS, and an EF-2 that directly struck Edgar in Clay County. On that same evening, very large hail up to 5.25" in diameter was reported near Montrose KS. On the 29th, tornadoes were primarily concentrated within Clay and York counties, including an EF-1 that tracked 16 miles from south of York to northeast of York, and crossed Interstate 80 approximately one mile east of the York interchange. (Please refer to the event story links at top of this page for much more detail on events on the 19th, 27th and 29th). Localized severe storms also occurred on the 25th and 26th, featuring golf ball size hail in Gothenburg and 2-inch diameter hail in northwestern Valley County. 

- Number of Severe Thunderstorm Warning polygons issued by NWS Hastings in May 2013: 101  (68 fewer than 2012's total of 169)

- Number of Tornado Warning polygons issued by NWS Hastings in May 2013: 27  (15 more than 2012's total of 12)
- Preliminary number of confirmed tornadoes within the NWS Hastings coverage area in May 2013: 13 (1 EF-3; 1 EF-2; 5 EF-1; 6 EF-0)

Hourly precipitation estimates from WSR-88D NEXRAD radar are compared to ground rainfall gauge reports, and a bias (correction factor) is calculated and applied to the radar field.
