Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 306 AM EDT Tue Sep 22 2020

SYNOPSIS. A deep strong and elongated surface high extends down the Atlantic coastline while a stalled frontal boundary is located across the Florida Straits. Aloft, weak west-northwest flow resides over the Peninsula as we are located on the northeast side of a weak upper-level anticyclone currently over the Gulf. For the tropics, Hurricane Teddy is currently northwest of Bermuda, taking aim at portions of Nova Scotia as it is expected to transition into a powerful post- tropical cyclone. Meanwhile, Tropical Storm Beta is right at the coast of Central Texas and this system is expected to move northeast along the coast over the next couple of days.

DISCUSSION. A tight pressure gradient exists across the Western Atlantic courteous of Hurricane Teddy and the aforementioned area of high pressure. This gradient has been enhanced by an existing surface front which is stalled across the FL Straits. These stiff northerly winds pivot to the northeast and then east as they feed into the inflow of TS Beta. Although still breezy, fortunately for us the winds will be a little weaker than we've see in the past couple as Teddy will shunt the high pressure south through the day, resulting in a relaxation of the gradient flow. Easterly wind surges will occur over the offshore waters during the overnight hours over the next couple of nights, but these should remain in the 15-20 knot range - nothing like the last day or two.

A dry continental airmass continues to filter into the area which is evident by dew points in the 50s across northern FL, and 60s across the Nature Coast. PWATs will hover around the 1 inch mark throughout the day, keeping our rain chances very low today and near nil tomorrow. Some high and low cloud cover is still possible today as moisture resides on either side of an extremely dry 850mb-450mb layer. CAM guidance, however, is still in good agreement on some isolated shallow-top showers streaming off the east coast and sagging southward through the day. Today and tomorrow, highs in the mid to upper 80s will be offset by noticeably (not significant, of course) less humid conditions. Adding in the breezy northeast to east winds, it will feel pretty nice when compared to the last several months. Cooler overnight temperatures will also prevail as much of the area should experience the 60s around sunrise. The lowest dewpoints will spread south later tonight, so temps should be a little cooler tomorrow morning compared to our lows this morning. Wouldn't be surprised if a few isolated cooler spots in Levy county reach the 60 degree mark overnight tonight.

Thursday still looks to be a transition day as surface high pressure slides off the SE coast, shifting winds out of the southeast. At this time, moisture only looks to be sufficient enough by the afternoon hours for convection to initiate across the southern half of the area - although this is By Friday, a weak surface trough looks to pivot on the western flank of the subtropical ridge and move northward into the SE Gulf of Mexico. This will result in a return of a deep tropical airmass, and accompanying rain, to be advected northward into the FL Peninsula. It is worth noting that the NHC has a very low 10% for development of this system. Regardless, area of disturbed weather looks to produce high rain chances through the weekend.

On Monday, a cold front will be approaching our area as troughiness sets up across the eastern half of the CONUS. Under the right front entrance region of the upper-level jet, the additional kinematic support will allow for some showers and storms out ahead of the front. The front looks to be in our CWA by the end of the period on Tuesday morning.

AVIATION. (06Z TAF) VFR category and rain-free conditions through the TAF period as drier air moves into the region. Northeast winds around 7-11 knots overnight will pick up by mid morning, becoming gusty to around 20 knots. These gusty winds then subside after sunset.

MARINE. Small Craft Advisory conditions are expected to continue through mid morning for all of the eastern Gulf waters, including Tampa Bay. We will see gradually improving conditions throughout the day as winds and seas will slowly be diminishing. They will temporarily increase again during the overnight hours as easterly surges bring headlines, if not brief advisory conditions each night. Otherwise, drier conditions will prevail across the coastal waters until moisture begins to return Thursday due to the presence of southeast flow.

FIRE WEATHER. Drier air will filter into the area through mid week. Breezy northeast winds will once again prevail today, although winds will be less than yesterday . This will translate to very good afternoon and overnight dispersions once again due to moderately strong dispersions. Otherwise, adequate moisture over the last week or two precludes any other fire weather concerns .
