389 FXUS62 KTBW 181410 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 1010 AM EDT Fri Oct 18 2024 ...New UPDATE... .UPDATE... Issued at 945 AM EDT Fri Oct 18 2024 A beautiful day setting up across West Central Florida with tempeatures getting to around 80 degrees this afternoon. No changes needed to the forecast at this time. && .DISCUSSION... Warming and moderating trend to begin today as upper low moves off the Mid Atlantic and weak upper ridging from the NE Carib nudges into the region. At the surface, the strong high pressure center that is north of the state will continue to produce a tight pressure gradient with breezy NE winds that will increase low level dew points. The weak upper ridge is expected to move over the state Saturday then shift into the Gulf Sunday as the persistent surface high pressure area remains over the Eastern U.S. with temps warming back to above normal values while the dry mainly rain free conditions continue. Next week expect an upper low in the W Atlantic with upper ridging in the W Gulf producing dry NW flow aloft while the surface high pressure area finally weakens mid week. A weak back door cold front is then expected to move into the region late next week. Guidance keeps PoPs 10% or less through the 7 day forecast period as well. && .AVIATION... (12Z TAFS) Issued at 805 AM EDT Fri Oct 18 2024 VFR conditions with gusty winds out of the north and northeast throughout the daytime hours. && .MARINE...
