Area forecast discussion, Jul 8, 7:00 PM EDT, 29 minutes before
Area Forecast Discussion...UPDATED National Weather Service Peachtree City GA 700 PM EDT FRI JUL 8 2016 .PREV DISCUSSION... /Issued 350 PM EDT FRI JUL 8 2016/ SHORT TERM /Tonight through Saturday Night/... Current radar loop shows some isolated showers and thunderstorms across Central and extreme North Georgia. The main area of convection is still across Tennessee and Kentucky and moving slowly south and east. the HiRes models are not in very good agreement with the timing and intensity of this wave affecting GA but they do agree that it will. Just looking at the way they initialized it appears the 4kWRF has the best handle on this and it shows the complex of thunderstorms moving into N GA around 22z- 23z. It also shows this complex diminishing as it moves south into the area with very little remnants left over the area by 03z- 04z. This appears to fit well with SPCs Day 1 marginal risk across North and eastern portions of the state. The HiRes models seem to be in a little better agreement for Sat...showing scattered showers and thunderstorms across the entire area as next wave moves in with upper level West to Northwesterly flow. Diurnally driven instabilities also increase across the area Sat so this also matches well with SPCs day 2 outlook thinking of just a General risk across the state. Heat Index values are still expected to get into the 105-108 degree range Sat afternoon across portions of East Central GA. Will need to issue another Heat advisory for a similar area as today for Sat afternoon. 01 LONG TERM /Sunday through Friday/... Made a few tweaks to the extended portion of the forecast. An unsettled period of weather is expected from Sunday through early next week. A weak boundary will remain situated across northern GA through Monday/early Tuesday, but should become diffuse by the middle of the week. The mid level flow will remain slightly nw/w through the period...and perturbations in the flow are expected to interact with the boundary...serving to focus scattered showers and thunderstorms. PWATS at or above 2 inches are expected into Tuesday...so any storms will be very efficient rainfall producers. Ridging tries to build in for the middle part of the week. However, models are keeping a weakness in the ridge overhead. The highest pops should remain across northern GA through much of the extended period. Have adjusted values slightly upward Sunday through Tuesday. NListemaa && .AVIATION... 00Z Update... VFR conditions expected to continue. Isolated showers/storms around ATL will dissipate by later evening. Surface winds diminishing to WSW around 5 kts or less for the overnight. High level ceilings possible late tonight and early Saturday. Chance for afternoon showers/storms on Saturday with surface winds around 10 kts with gusts near 20 kts. //ATL Confidence...00Z Update... Low confidence for effects of any evening showers/storms. Medium to High confidence all other elements. && .PRELIMINARY POINT TEMPS/POPS...
