. Afternoon AFD for April 19 .
SHORT TERM /Tonight through Tuesday Night/.
Fire Danger Statement out today for portions of central and eastern GA where RHs are going to drop this afternoon into the lower to mid 20s. Dry air is noted aloft well within range of mixing heights today which will help us mix out some of the little remaining atmospheric moisture we have. Little previous rains has created some dry fuels, so take care if doing any burning of any remaining winter debris in these areas and check with local authorities to ensure that burning is permitted. See the the /SPSFFC/ product for specific counties. Otherwise, beautiful day across the area with only a few fair weather cumulus across north GA. Temps have already bounced into the 60s and 70s and winds are from the northwest between 5-10 mph with a few higher gusts as some of the dry air aloft mixes down.
500 mb shortwave that has ejected from the 4 corners region into TX today will move across the area quickly tonight into tomorrow. Baroclinic frontal boundary is well into the Gulf of Mexico and across the FL peninsula, so any expected moisture return looks to remain south of the area, with only some high cloud cover expected tomorrow morning into the afternoon. Have taken out all mention of even slight PoPs in the forecast area with this package as models continue to trend drier. The good news about this cloud cover tomorrow is that it may prevent us from heating and mixing out moisture quite as much as today, so at this time it does not look like a fire danger statement will be needed, though this will need to be reevaluated in the overnight package, as RHs will still be low. Winds will flip to the south, but should be weaker than today. Upper level system moves quickly by the area and clears out by tomorrow night ahead of larger trough with cold front progged to move into the area Wednesday, where the long term takes over.
LONG TERM /Wednesday through Monday/.
Quiet and dry will be the main stories of the long term forecast with the CWA starting out between two frontal systems and weak high pressure over the area. As mentioned, not too much change through the week aside from trough aloft ejecting a dry cold front across the area on Wednesday. PoPs won't be much concern, however, with our already dry fuels in combination with higher winds and low RH values, fire danger will need to be monitored. After the frontal passage, expect low temps to become unseasonable cold, near 9-12 degrees below average for this time of year. With green up already occurring, will need to monitor the potential for frost/freeze products for Wednesday night and Thursday night, especially across portions of North GA.
Still slight inconsistencies in regards to spatial coverage and timing, but overall model guidance is coming into better agreement that the next chance for precip could come next weekend as a surface low develops over the Oklahoma handle and pushes eastward. Current QPF values through the weekend range between 1.5-2.5", with the axis of heaviest values along the I-85 corridor.
AVIATION. 18Z Update . Scattered fair weather Cu are across north GA including some of the metro TAF sites and AHN. These should fade with sunset. Otherwise, VFR conditions through the period at all sites. Winds today will be 7-12 kts from the N to NW. Tonight, some high cirrus expected to move in as most sites go VRB. Will see wind shift at ATL tonight around 07-08Z to the NE, with winds going southerly tomorrow at all sites from 5-9 kts. BKN skies in the morning should go SCT by afternoon.
//ATL Confidence . 18Z Update . High confidence in all elements.
