Area Forecast Discussion National Weather Service Tallahassee FL 300 PM EDT Sat Mar 28 2020

NEAR TERM [Through Sunday].

Near record heat will repeat into Sunday with highs around 90 degrees away from the gulf coast. For some perspective, average highs are in the middle 70s.

Fog is likely again tonight and Sunday morning, but it should be more patchy compared to the extent observed this morning. The highest confidence in areas of dense fog is from the eastern FL Big Bend northward into portions southwest GA.

An approaching cold front could lead to an isolated shower and rumble of thunder west of the Flint River into the Wiregrass region Sunday afternoon.

SHORT TERM [Sunday Night and Monday].

No major weather concerns during this time frame . continued dry and very warm. High temperatures in the middle 80s to around 90 degrees. The pattern looks less favorable for fog Monday morning.

LONG TERM [Monday Night Through Saturday].

The main concern during this period is the potential for severe weather centered on Tuesday. A progressive, neutral tilt southern stream shortwave will move across the Tennessee Valley with an associated upper level jet maxima around 100 kts. Considerable uncertainty given some of the more favorable parameters may be out of phase, including questionable instability and mid-level lapse rates. With the strong wind field in place and drier air mass advecting in aloft, there is at least a damaging wind threat.

AVIATION. [Through 18Z Sunday]

VFR will deteriorate to widespread IFR/LIFR in low clouds and patchy fog after 00Z, with gradual improvement to VFR 12-15Z. Southwest winds of 10-20 knots today become light and variable tonight, then resume on Sunday around 5 to 10 knots.

MARINE.

Southerly winds will prevail through Monday with seas around 3 feet or less outside of Apalachee Bay. Winds and seas will increase on Tuesday and Wednesday up to Small Craft Advisory levels. Thereafter, more tranquil boating conditions will return for Thursday and Friday.

FIRE WEATHER.

A spot shower or rumble of thunder is possible Sunday afternoon west of the Flint River into the Wiregrass region. Otherwise, a very warm and dry period of weather is on tap through Monday. Elevated mixing heights and southwest transport winds could yield high dispersions Sunday afternoon across much of the area away from the Gulf coast. Red flag conditions are not expected through the forecast period.

HYDROLOGY.

Mostly dry conditions expected through weekend. A strong cold front moving in on Tuesday into Wednesday does not look to bring widespread heavy rain so flooding concerns aren't anticipated at this time.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
