036 FXUS62 KTBW 111123 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 723 AM EDT Sat May 11 2024 ...New AVIATION... .DISCUSSION... A weak frontal boundary is over N FL with a broken band of weak showers well ahead of it that continues to slowly sag over the C FL Peninsula early this morning through daybreak. The rain and frontal boundary will be across the southern part of the peninsula later today, while drier air and high pressure filters into N FL. The high pressure center quickly moves into the W Atlantic Sunday with a warm and dry Mother`s Day expected. The next southern tier storm system is expected to develop and move through the N Gulf region Monday with winds becoming E-SE increasing moisture. The main dynamics and surface low are expected to remain well N of the area as the weakening attendant cold front stalls in N FL. The S-SW low level flow will persist with modest instability and diurnal heating will increase much needed rain chances for the area Tue-Fri. && .AVIATION... (12Z TAFS) Issued at 721 AM EDT Sat May 11 2024 Occasional MVFR CIGs will be possible to start the TAF period as a band of light showers gradually pushes southward. The shower activity should quickly taper off by mid to late morning with drier air building in and this will provide for VFR conditions for the remainder of the period. Winds will generally be from the west-northwest at around 8-12 kts but occasional stronger gusts will be possible at times. && .MARINE... A weak frontal boundary continues to slowly move through the area as high pressure builds into the Northern Gulf with northwesterly winds. The high pressure area will quickly move into the Western Atlantic with winds swiftly to the east and then southeast Sunday into early next week. Another front moves into the region Tuesday with southwest winds increasing to near exercise caution levels with increasing rain chances as well. && .FIRE WEATHER... Weak high pressure is expected to build into the region this weekend with drier air moves into the area, especially on Sunday, but winds are expected to remain below critical criteria preventing Red Flag conditions. Low-level moisture and rain chances are expected to increase next week. && .PRELIMINARY POINT TEMPS/POPS...
