Area forecast discussion, Jun 17, 2:51 PM EDT, 1 hour 22 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 251 PM EDT Sun Jun 17 2018 .SHORT TERM /Tonight through Monday Night/... Continued more of the same with afternoon showers and thunderstorms cross the area today and monday. Will also see more low clouds and fog in the morning with a very weak summertime pattern in place across the region. The main features across the area continue to be the large upper level ridge and the weak upper level disturbance that have been rotating over GA/AL/Northern FL and continue to help enhance diurnally driven convection everyday. The ridge has been helping to suppress the activity but it is also keeping this weak pattern in place with no signs of this changing anytime soon. still expecting strong storms to develop in the short term with isolated severe storms as well. The greatest threats will be gusty winds, frequent lightning, period of heavy rain and small hail. For those with outdoor activities planned today, stay weather aware. If you can hear thunder, you are close enough to be struck by lightning. You should seek shelter if you see lightning or hear thunder. In addition, Heat Indices will range from the middle to upper 90s across much of the state today and Monday. If you plan on being outdoors for long periods of time, take frequent breaks to cool off and stay hydrated. 01 .LONG TERM /Tuesday through Sunday/... Long term period begins with the continued pattern of mid and upper level ridge firmly entrenched over the area but plenty of moisture trapped at the low levels under this feature. This pattern will continue into Wed and the first part of Thu characterized by low to mid range chance pops and mainly a heavy rain potential as mid levels warm to -5C at 500mb. Ridge does flatten out a bit into late week as shortwave energy flows in from the central plains and travels across northern portions of the Tennessee Valley. This will allow for a temporary increase in pops across the northern CWA by Friday afternoon. Main moisture axis and energy looks to remain north of the area thereafter and a return to low to mid range sct pops looks in the offing. Did reload latest long term guidance but left pops largely alone as they represent above thinking well. Deese && .AVIATION... 18Z Update... More diurnal convection today and Monday. Ceilings are in the MVFR to VFR range across the area and will eventually become all VFR later today. Will see more MVFR and some IFR ceilings move back in overnight through Mon morning. Ceilings will lift through Monday afternoon similar to this morning. Winds are expected to be mainly out of the SW at 8kt or less. Will see some gust to near 20kt in and around any TSRA development this afternoon and Monday afternoon. VSBYs will stay VFR except some brief periods of IFR VSBYs in and around thunderstorms activity. //ATL Confidence...18Z Update...
