Dothan Area Weather Forecast May 12

NEAR TERM [Through Monday]...

The highly amplified long wave pattern persists across North America
this afternoon with a trough dominating the eastern half of the
continent. Surface low pressure is centered over New England with
a cold front trailing southwestward from it. The southern end of this front is still moving slowly across the southeastern FL Big Bend. A second front is poised to enter our northwestern zones.

A few of the convection allowing models, including our local WRF, continue to show isolated showers developing along and just ahead of the lead front around or shortly after 18Z. We will therefore leave in a small area of 20 PoPs for Taylor, Lafayette and Dixie Counties. Any showers that develop will dissipate by sunset.

The second front will surge across the forecast area overnight bringing another unseasonably cool airmass to the Gulf Coast.

Lows tonight will drop 8-12 degrees below normal along and north of I-10 with many areas north of the FL border actually dipping into the upper 40s. The very dry airmass will allow temps to warm quickly after sunrise. However, temps will still be below normal peaking in the upper 70s to around 80 degrees. All in all, it should be a very pleasant day.

SHORT TERM [Monday Night Through Wednesday]...

The deep upper level trof pushing the cold front through today will
lay over the mid-Atlantic states by Monday night and an upper level
ridge will be building eastward over our area through the period.

High pressure at the surface and aloft through the period will give
us clear skies.

Monday night will be a little chilly with lots of radiational cooling allowed from the clear skies in addition to the presence of a much colder air mass. Lows will dip into the mid-upper 40s across the region. Tuesday the clear skies will allow us to warm up again to the low 80s. Lows Tuesday night will be in the 50s and highs Wednesday will be in the low-mid 80s.

LONG TERM [Wednesday Night through Saturday]...

Although models are showing upper level ridging at 300 mb that stays
in place through the period, they also show a mid-level short wave
impulse at 500 mb that will propagate through the weak ridging. This
may cause some convection this weekend, particularly during daytime
hours with solar heating to aid it, but the models are not showing high rain chances overall this weekend, with PoPs highest on
Saturday and Sunday during the day with values <30%.

Temperatures will be about normal for this time of year.

AVIATION [Through 18Z Monday]...

VFR conditions are forecast throughout this TAF period.

VFR ceilings of 4-5 kft are expected this afternoon at TLH and VLD.
The main aviation impacts on Monday will be the gusty north winds.

MARINE...

Behind the dry cold front passage, the pressure gradient will increase and winds will pick up to advisory levels over the coastal
waters from west to east overnight.

Waves will increase to as high as 5 feet offshore.

Winds will begin to settle down to cautionary levels from north to south through Monday morning through Monday night and after that, winds and seas will remain below advisory level for the rest of the period.

FIRE WEATHER...

A drier air mass has arrived behind a cold front across all but
southern and eastern portions of the FL Big Bend.

However, red flag criteria will not be threatened.

On Monday, red flag conditions are definitely a possibility across a few of our FL zones, namely Bay, Calhoun, Leon and Wakulla. It will definitely be dry enough with min RH getting into the upper teens and lower 20s. Winds will be marginal, but observed ERC levels are high enough in the aforementioned counties.

We will mention these caveats in the remarks, but winds are too marginal to go with a watch or warning at this time.

Red flag conditions are unlikely in Alabama and Georgia due to insufficient KBDI and fuel moisture requirements respectively.

HYDROLOGY...

Rainfall totals on Saturday were minuscule, so we don`t expect any
hydrology issues for the next several days.
