DAY 3-8 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0217 PM CDT SUN APR 26 2015

VALID 281200Z - 041200Z

MEDIUM RANGE MODEL GUIDANCE IS IN GOOD AGREEMENT THROUGH MUCH OF THE
DAY 3-8 PERIOD. MAINLY QUIESCENT FIRE WEATHER CONDITIONS ARE
EXPECTED. THE EXCEPTION MAY BE SOME ELEVATED CONDITIONS ACROSS
PORTIONS OF THE NORTHERN PLAINS BY MID TO LATE WEEK.

THE UPPER LEVEL LOW OVER THE SOUTHERN PLAINS ON DAY 3/TUE WILL TRACK
EASTWARD...BECOMING AN OPEN WAVE OVER THE MID AND LOWER MS VALLEY.
THIS SYSTEM WILL MERGE WITH ANOTHER UPPER LOW DROPPING SOUTHEAST OUT
OF CANADA AROUND DAY 5/THU OR DAY 6/FRI AND SLOWLY CONTINUE TO LIFT
NORTHEAST OFF THE ATLANTIC COAST THROUGH THE END OF THE PERIOD. IN
THE WAKE OF THIS UPPER TROUGH/LOW SYSTEM...AN UPPER RIDGE OVER THE
WESTERN U.S. WILL TRACK ACROSS THE ROCKIES TOWARD THE PLAINS. THE
RIDGE WILL BEGIN TO BREAK DOWN ON DAY 4/WED AND 5/THU AS AN UPPER
SHORTWAVE TROUGH TRACKS EAST ALONG THE U.S./CANADIAN BORDER IN THE
VICINITY OF THE NORTHERN ROCKIES. ANOTHER SHORTWAVE WILL FOLLOW
QUICKLY ON ITS HEELS ON DAY 6/FRI AND DAY 7/SAT. THE ASSOCIATED
SURFACE LOW/TROUGH THAT DEVELOPS OVER THE NORTHERN HIGH PLAINS
COMBINED WITH ENHANCED DEEP LAYER WESTERLIES COULD LEAD TO SOME
ELEVATED FIRE WEATHER CONDITIONS. HOWEVER...UNCERTAINTY IN RH VALUES
AS WELL AS PRECIPITATION POTENTIAL OVER THAT REGION THE NEXT FEW
DAYS WILL PRECLUDE THE INCLUSION OF ANY HIGHLIGHTS AT THIS TIME.
