TONIGHT AND WEDNESDAY...
HIGH PRESSURE CONTINUES TO PREVAIL OVER THE REGION, KEEPING US WARM
AND DRY. TEMPERATURES GENERALLY REACHED THE UPPER 80S AND LOW 90S
TUESDAY AFTERNOON. LOWS TONIGHT WILL FALL INTO THE MID AND UPPER
60S. PATCHY FOG WILL ONCE AGAIN BE POSSIBLE ACROSS PARTS OF THE
FORECAST AREA, ESPECIALLY IN LOW LYING AREAS, WHERE CROSSOVER
TEMPERATURES ARE REACHED AND WINDS DIMINISH.
ANY FOG THAT DOES DEVELOP SHOULD BURN OFF SHORTLY AFTER SUNRISE
WEDNESDAY. HIGHS WILL BE SIMILAR TO THE LAST FEW DAYS, IN THE UPPER
80S AND LOW 90S.
FRIDAY AND BEYOND...
TEMPERATURES CONTINUE TO RAMP UP AS WE HEAD INTO THE LATTER HALF OF
THE WEEK. HIGHS ARE EXPECTED TO REACH THE MID TO UPPER 90S BY FRIDAY
AND SATURDAY, WITH SEVERAL LOCATIONS POTENTIALLY REACHING 100 ON
SUNDAY. WHILE NOT OVERLY EXTREME, DEWPOINTS HAVE CONTINUED TO TREND
SLIGHTLY HIGHER THAN GUIDANCE RECENTLY. IF THIS CONTINUES THROUGH
THE WEEKEND, HEAT INDICES MAY REACH 100-105. MEANWHILE, OVERNIGHT
LOWS ARE FORECAST TO REMAIN IN THE LOWER 70S, PROVIDING LITTLE
RELIEF FROM THE DAYTIME HEAT. WHILE CERTAINLY NOT A SLAM DUNK, HEAT
HEADLINES MAY NEED TO BE CONSIDERED FOR FRIDAY THROUGH SUNDAY.
A LOW PRESSURE SYSTEM MOVING OUT OF CANADA TOWARD THE GREAT LAKES
WILL WORK TO FLATTEN THE UPPER RIDGE LATE THIS WEEKEND. WHILE BETTER
PRECIPITATION CHANCES WILL UNFORTUNATELY SKIRT THE FORECAST AREA,
THIS SYSTEM WILL DRAG A COLD FRONT THROUGH THE CENTRAL PLAINS,
BRINGING US SOME RELIEF FROM THE HEAT.
BEHIND THE FRONT, NORTHWESTERLY UPPER LEVEL FLOW APPEARS TO RETURN.
IF THIS REMAINS THE CASE, WE COULD SEE A FEW SHORT WAVES ROUNDING
THE RIDGE AND BRINGING PRECIPITATION CHANCES BACK TO THE REGION.
