944 FXUS62 KFFC 071146 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 746 AM EDT Thu Apr 7 2022 ...Updated for 12Z Aviation Discussion... .PREV DISCUSSION... /Issued 356 AM EDT Thu Apr 7 2022/ ..Generally Dry, Chilly Remainder of the Week as Storm Cleanup Continues... SHORT TERM /Today through Friday/... Line of convection continues to push south and east through middle Georgia this morning, losing its punch as it goes. Expect it to clear the CWA by mid morning at the latest, with clearing conditions behind it. Breezy and sunny conditions are expected today, though winds should stay sub-Wind Advisory criteria. Near seasonal temperatures are expected today with highs in the 60s and low 70s. By Friday morning, low temperatures will drop into the 40s over the area, except mid to upper 30s over northeast Georgia. Highs Friday will be much cooler, running 7 to 17 degrees below climatology (highs in the 50s and 60s). Large parent low over the Midwest will circulate and slide eastward, extending large wrap-around moisture field back into north Georgia by Friday. Forecast models are in good agreement with adding slight chance to chance PoPs back over the far tier of north Georgia counties mid-morning Friday and into the evening hours. There is some uncertainty whether moisture will hold over far northeast Georgia into the overnight period, which may be a concern for a brief, light wintry mix as cooling temperatures combine with exiting moisture just after midnight Saturday morning. 31 LONG TERM /Friday Night through Wednesday/... Aforementioned broad low pressure system will slowly progress eastward over the Great Lakes/Canada into the weekend, with several pulses rounding through the trough and keeping low-end PoPs over north Georgia Saturday. Dry northwest flow will reinforce cooler air over the state, with lows Saturday morning and again Sunday morning settling into the low to mid 30s. While dew points may be too dry for areas of frost development, have included 'patchy frost' in the grids for portions of north Georgia both Saturday and Sunday. Frost/Freeze products may be necessary for this period. Reminder - the Frost/Freeze program for far northeast Georgia will begin April 15. Recent heavy rainfall could make drying difficult, but Fire Weather may once again be a concern late in the weekend given minRH values in the low to mid 20s. Will need to monitor evaporation/green up under sunny skies over the next few days to determine risk. Forecast remains dry into early next week with moisture increasing around the periphery of upper level ridge by Monday afternoon. Models are in decent agreement with steady, messy moisture axis over the region through Wednesday, with hope of a cold frontal passage late Wednesday/early Thursday to sweep it out. There is still high uncertainty on potency of this low/frontal system and timing of it pushing through the state. Stay tuned, but at least for now we can rest that SPC has not included any early outlook for Day 8 for the state. 31 && .AVIATION... 12Z Update...
