Area forecast discussion, Jul 3, 3:35 PM EDT, 3 hours 10 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 335 PM EDT Fri Jul 3 2020 ...Afternoon Forecast Discussion for Friday, July 3rd... .SHORT TERM /Tonight through Saturday Night/... A large-amplitude synoptic ridge continues to reside over the eastern two-thirds of the CONUS, with a mid-level positively tilted trough axis that was draped into the Southeast continuing to erode away. In the low-levels, a typical, moist summer-time airmass resides with PWATS between 1.2-1.6 inches through the forecast area. A stationary boundary is also oriented from roughly Birmingham to Brunswick, which will act at a focus for convective development this afternoon. Near this boundary, in the southern and west central portions of the forecast area, rain and storm chances will be near 25-35 percent, with 10-20 percent chances elsewhere. MLCAPE values are better to the south and west which will help with convective development, but low mid-level lapse rates from the weak subsidence from the upper-level trough should keep storms from being too strong in the Southeast today. For Independence Day, a similar forecast in storm with the focus for better shower and thunderstorm development shifting towards North Georgia, topping out around 35-40 percent for most areas along and northwest of the I-85 corridor. For central Georgia, rain chances go from 15 percent to 30 percent as you go from east to west. Highs are forecast in the low to mid 90s with morning lows generally around 70, which is running just slightly above climatological norms, with heat indices around the upper 90s to low triple digits today for much of central GA. Thiem .LONG TERM /Sunday through Friday/... A persistently damp forecast characterizes the long-term forecast period, bringing ample opportunity for showers and thunderstorms through the week ahead. A very sluggish upper low will begin the week centered over the Lower Mississippi Valley, spreading anomalously abundant moisture northward across the forecast area, especially by Monday. PWATs will surge over 2", and the deep moisture will persist through the week. With such a moist environment, locally heavy rainfall will be a concern with the numerous showers and thunderstorms that develop each day. Coverage will be maximized each afternoon and evening as heating increases, though lingering showers and thunderstorms will remain possible into the overnight hours. With the upper low remaining cut off from the synoptic flow, it will make very little progress through early week. Models are in fairly good agreement that the low will begin to drift eastward and center over the Appalachians/Carolinas by Wednesday into Thursday as high pressure builds from the west. With this gradual transition eastward, high PoPs appear likely to prevail at least through late week. High temperatures through the coming week will be moderated by widespread clouds and rainfall and likely be relegated largely to the lower 80s during the early week, several degrees below July normals. However, given the rich moisture in place, overnight lows will remain slightly above normal. RW && .AVIATION... 18Z Update... Mostly VFR conditions expected for the forecast area through the TAF period with slightly less SHRA/TSRA chances expected today than from previous forecasts and the CU field around 4-5kft. Winds will be light and out of the east to southeast becoming near calm overnight. Slightly better chances for SHRA/TSRA for northern sites and CSG tomorrow. //ATL Confidence...12Z Update...
