Precipitation for November 2013 varied from below normal across the northwest third of the HSA, to above normal across most of the southeast third of the HSA. A strong storm system brought widespread moderate to heavy rains to most of the HSA late on the 4th to early on the 6th. As much as one-half to three-fourths of the month’s precipitation occurred with this one storm system. A passing low and cold front brought light rain to mainly the north end of the HSA on the 9th. Another passing cold front brought light rain and the first measurable snow to most of the HSA on the 11th. A stronger low and cold front brought light to locally heavy rains to mainly the southeast half of the HSA on the 16th into the 17th. Another low and cold front produced light rain and snow across most of the HSA on the 20th to 22nd, with some moderate snow across the far north end of the HSA. A cold front brought a narrow band of moderate to heavy snow to the far south end of the HSA on the 25th into the 26th. A weak disturbance aloft brought some light snow to the north end of the HSA on the 28th.
Normal precipitation for November varies from 1.75 inches over the northwest end of the HSA to near 2.5 inches over the east end of the HSA. Totals for the month ranged from 50 to 80 percent of normal over the northwest third of the HSA, to 100 to 150 percent of normal across the southeast third of the HSA. Most rainfall totals for November were 80 to 125 percent of normal. Extreme totals recorded for the month ranged from 0.80 inch at near Dodge Center in Dodge Co. MN and 0.95 inch at Lock/Dam 4 near Alma in Buffalo Co. WI, to 3.55 inches at Mauston in Juneau Co. WI and 3.75 inches at Soldiers Grove in Crawford Co. WI.
November snowfall was below to above normal across the HSA, ranging from 4 to 8 inches across the far north end and a small portion of the far south end of the HSA, to mostly one-half to 2 inches elsewhere. Normal November snowfall ranges from around 3 inches in the southeast end of the HSA, to 6 to 7 inches across the west and north ends of the HSA. Most snowfall totals this month were 20 to 70 percent of normal.
Temperatures for November 2013 averaged 30 to 35 degrees. This was 1 to 4 degrees below the normals. Temperatures were slightly above to slightly below normal from the 1st to the 10th then below to much below normal for the 11th to the 13th. Near to above normal temperatures occurred from the 14th to the 21st, but for one much above normal day on the 16th and a below normal day on the 18th. The 22st to 24th brought below to much below normal temperatures as did the 26th to 29th. Temperatures were above normal on the 25th with the month ending with much above normal readings on the 30th. Extremes for the month ranged from lows of 5 below to 10 above on the morning of the 24th, to highs in the 50s to around 60 on the 16th.
Flows in the rivers and streams of the HSA were generally near normal for this November. Some improvement to the drought conditions occurred over the southeast third of the HSA but abnormally dry to locally severe drought conditions persisted across much of the HSA at the end of the month. By the end of the month most agricultural progress and field work activities were close to normal. Due to the below normal temperatures and minimal snow cover later in the month, ground frost and ice cover on the rivers, streams and lakes of the HSA were above normal at the end of the month.
