SYNOPSIS. Issued at 348 AM EDT Thu Apr 22 2021
Temperatures will finally moderate today with highs rising close to 50 this afternoon as an upper level ridge builds into the area. Frost is likely tonight before the warming trend continues into Friday. Rain is expected to develop Friday night and continue into Saturday with highs in the 50s. Conditions will be dry Sunday through Tuesday with summer-like weather Tuesday and highs in the lower 80s.
SHORT TERM. (Today and Tonight) Issued at 348 AM EDT Thu Apr 22 2021
Temperatures will finally moderate today with highs rising close to 50 this afternoon as an upper level ridge builds into the area. Will let the freeze warning stay in effect as temperatures continue to fall slowly early this morning. Afternoon highs should recover to near 50 degrees. Frosty conditions are expected for one more night as lows drop to around freezing tonight. Given the ongoing freeze warning in effect, did not issue a frost advisory, but will defer any issuance to the next shift.
LONG TERM. (Friday through Wednesday) Issued at 348 AM EDT Thu Apr 22 2021
Two upper level systems will bring two rounds of precipitation to the forecast area this period. The initial short wave will have somewhat limited moisture available Saturday. Have kept thunder out for now with somewhat limited moisture and instability. Otherwise, an upper level ridge will build across the Midwest in response to an upper level trof developing upstream. Highs should reach the lower 80s Tuesday. Much higher precipitable water values will be over the area approaching 1.6 inches per GFS Wednesday. There is a chance for thunderstorms with heavy rain during the middle of next week.
AVIATION. (For the 12Z TAFS through 12Z Friday Morning) Issued at 630 AM EDT Thu Apr 22 2021
The last in the series of upper level short waves is dropping across the southern Great Lakes this morning. Moisture is quite limited with this short wave with just an increase in 5-8 ft clouds for a brief time early this morning. Deep layer subsidence to build in behind this short wave later this morning with mainly clear skies for this afternoon as subsidence inversion becomes more pronounced. Mid level cold pocket will be shifting east of the area today but continued diurnally enhanced steep low level lapse rates should promote some westerly gusts to around 20 knots late morning into this afternoon. Winds to diminish abruptly early this evening, with an increase in high clouds later tonight as upper level ridge axis shifts across the western Great Lakes.
