DISCUSSION.

. A Chilly Night Ahead .

Tonight . The pressure gradient will weaken with surface high pressure becoming centered over southern MS/AL this evening and tonight. Winds becoming light combined with dry air and clear skies will let temperatures drop off quickly after sunset. The cool, dry advection will continue overnight and with the favorable conditions for radiational cooling, low temperatures are expected to come within a couple of degrees of their dewpoints. This will put overnight lows around 40 degrees except a few degrees warmer around metro Orlando and also along the barrier islands. Some of the more wind-sheltered locations are more likely to reach the upper 30s.

Sunday . Dry, subsident airmass stays in place to finish up the weekend. After a chilly start, temperatures will recover nicely, but an increase in cirrus overhead is expected to keep highs slightly cooler than those of today. Forecasts highs are mid to upper 60s most and closer to 70 for the Treasure Coast, which are all slightly below normal for late January.

Sun night-Tue . Low pressure across the central Gulf Sun night will weaken as it approaches the FL peninsula. Guidance POPs have lowered with 12z guidance but will hold on to a slight shower chance over portions of east central FL on Monday. High pressure will build in twd N FL and the Southeast Tue behind a frontal boundary moving southeast off the southeast Atlantic coast. This should allow for dry north-northeast flow and temps near normal levels. Highs in the upper 60s to lower 70s and lows mainly in the upper 40s to lower 50s.

Wednesday-Saturday (modified) . Another fast moving positive-tilt short wave trough slides ESE along the Gulf Coast Wed, then shears out as it crosses north-central FL late Wed night-Thu morning. A flat short wave ridge will move across FL Thu-Fri, with another embedded mid level vort ripple sliding across FL Fri afternoon. By Fri night, a more substantial trough sill be pushing into the SE CONUS, although by that time, differences in timing and intensity start to become more apparent. However the trend is toward a more unsettled pattern by the end of next week.

12Z GFS has come into somewhat better agreement with the ECM on the track of the next low pressure system that will affect the area this weekend. Low pressure should develop across the central Gulf by Friday and move ENE to a position just off or near the southeast Atlantic coast late in the weekend. Have kept POPs close to the previous forecast around 50 percent Fri-Fri night, but these will likely be adjusted up a bit as we draw closer to this event. There also exists some potential for TS around that time, however since we're talking about a day 6-7 feature, prefer to hold off for now.

Rain chances should be minimal through Thu, then increase thereafter as mentioned earlier. Temps look to average slightly above normal.

AVIATION. VFR conditions continue through Sunday afternoon.

MARINE. Through tonight . Observations show seas just over 6 ft at Buoy 41009 and over 7 ft at Buoy 41010 so no changes to the headlines are needed. Exercise caution statements will remain across the nearshore waters through this evening will the SCA will continue offshore until 09Z/4am tonight. NW winds are forecast to diminish briefly but increase to around 15 kt again after midnight.

Sunday . Pressure gradient continues to weaken allowing NW/N winds to diminish to 5-10 kt. Some lingering seas of 6 ft offshore may prolong the exercise caution through late morning, but seas will subside through the day to 3-5 ft nearshore and 4-5 ft offshore.

Sun night-Mon . The pressure gradient will weaken late in the weekend with winds below 10 knots across the waters. Seas 3-5 ft Sun night will drop to 3-4 ft Monday in an ENE swell.

Tue-Thu . A weak front will move south across the waters Tue with northerly flow increasing on Tue. Winds will become NE/E into Wed with the approach of quick moving low that will cross N FL. N/NE winds expected Thu to 10-15 knots with high pressure near the mid Atlantic. Seas generally 3-4 ft increasing across the gulf stream Thu as northerly winds increase.

FIRE WEATHER. Sunday . Although winds are expected to remain less than 10 mph, min RH is again expected to fall to 30-35% across the interior during the afternoon.

Monday . Increased mid and high cloud cover is expected with afternoon Min RHs dropping to around 40 percent across the interior. Shower chances will remain low at 20 percent or less.
