Area Forecast Discussion National Weather Service Tallahassee FL 622 AM EDT Thu Apr 2 2020

AVIATION. [Through 12Z Friday]

VFR conds will prevail through the period with light north to northeast winds as high pressure dominates.

PREV DISCUSSION [210 AM EDT].

NEAR TERM [Today and Tonight].

Deep layer ridging will be in place through this period as mid level high is located in the southern Gulf and surface ridging is wedged between two systems. Today, cool and northeasterly surface winds are on tap as we are on the downstream side of the ridge but winds will become easterly tonight as the ridge shifts slowly eastward. Mostly sunny skies are anticipated today with a few high clouds tonight. Highs today will be in the 70s with lows tonight in the upper 40s to lower 50s.

SHORT TERM [Friday through Saturday Night].

Surface high pressure remains over the region on Friday as a ridge aloft holds firm between two upper level lows. The ridge and surface low shift east on Saturday as a weak cold front approaches from the west associated with an upper low over the upper midwest. With the slow progression, Friday through Saturday night should remain dry. Highs will be in the lower 80s Friday and a few degrees warmer Saturday. Lows will be in the lower to upper 50s.

LONG TERM [Sunday Through Thursday].

The upper low stays up in Canada with this front causing most of the front to weaken as it reaches the local area. Some guidance shows a low chance of pops and that seems reasonable. The low levels in the atmosphere remain fairly dry even with the front but we will see cloudy skies even if we don't see any rain.

Broad ridging then develops over the area with Sunday night remaining dry. The ridge has deep layer southwest flow with a stream of moisture coming in from around Baja California. This moisture along with weak shortwaves will leave isolated to scattered rain showers in the forecast through Thursday. Model differences still exist about how far north/south the shortwaves move which will ultimately decide how much rain we get and where. There are thunderstorms in the forecast Tue-Thu. Right now, instability and moisture look high but shear and forcing is weak so not expecting anything severe at this time.

Temps will be warming from the lower 80s Sunday to the upper 80s Wed/Thu. Lows will be warming into the upper 60s and will be near 70 Tue and Wed night.

MARINE.

Winds will generally be less than 10 knots with seas less than 3 feet through the forecast period. The next chance of any rain and thunderstorms will be past this forecast period, on Tuesday.

FIRE WEATHER.

Hazardous fire weather conditions are not expected over the next several days.

HYDROLOGY.

The Flood Warning for the Apalachicola River in Blountstown was cancelled as it has steadily fallen and is now below flood stage. Otherwise, there are no flooding concerns as total rainfall through the next 7 days will be less than half an inch.

SPOTTER INFORMATION STATEMENT.

Spotter activation is not requested. However, spotters are always encouraged to safely report significant weather conditions when they occur by calling the office or tweeting us @NWSTallahassee.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
