Area Forecast Discussion National Weather Service Tallahassee FL 129 AM EDT Tue Jul 27 2021

AVIATION.

[Through 06z Wednesday] Mainly VFR conditions are expected through the morning hours, although a brief period of MVFR conditions is possible at VLD around dawn. Scattered to numerous showers and thunderstorms are expected across the area this afternoon into this evening.

PREV DISCUSSION [1001 PM EDT].

NEAR TERM [Through Tuesday].

Surface low near the Georgia low country will move ashore this afternoon and weaken as it moves westward. The associated increase in tropical moisture, as well as a tropical wave moving through the Gulf, will advect from west to east into our area tonight and Tuesday. Chances of showers and storms this afternoon and evening will reside mainly on our eastern border however, the HRRR continues to advertise development in southeast Alabama early this evening so have raised rain chances slightly in our western zones. Not much in the way of convection is expected in the overnight and early morning hours. Rain chances increase markedly late morning Tuesday through the afternoon hours with scattered to numerous coverage of storms and chances around 70% throughout the area. Highs Tuesday will be in the low to mid 90s with heat indices in the low to mid 100s.

SHORT TERM [Tuesday Night Through Wednesday Night].

Across the upper levels, a shortwave vorticity maxima is expected to move through eastern Georgia and southern South Carolina late Tuesday night and into Wednesday morning. This is expected to provide ample upper level support across our SW Georgia regions to increase PoP chances through this time period. This upper level support coupled with a lingering weak surface low and high PW values greater than 2 inches from the current tropical wave moving into Jacksonville area will create an environment conducive enough for widespread showers and thunderstorms. This potentially could cause some nuisance flooding in streams and across drainage ditches with higher rainfall rates, especially if storms train or stay over the same areas for extended periods of time. Lows tomorrow night will be warm with mid 70s expected across the entire region. Highs will also be warm in the low 90s.

LONG TERM [Thursday Through Monday].

As the previously aforementioned shortwave vorticity maxima moves off the coast of the United States, upper level ridging is expected to become the prominent synoptic feature through the remainder of the long term period. As the peak of the ridge axis is expected to be out west, northwest flow aloft is expected to return to the region, especially across the southeast. As weak to moderate troughing develops to our north over the Northeast and the Mid-Atlantic regions, we can expect a few shortwave impulses to ride along the periphery of the trough axis to our north and potentially increase rain chances and severity on any given day through the long term period. With the trough axis to our north, and the deep upper level ridge to our west, extremely high PW values in the 2" range will drop to around 1.5-1.8 through the long term as some dry air advects into the region through the mid and upper levels. Overall, seasonable rain chances are expected to return via diurnal convection that will encompass the area through the afternoon and evening hours. Currently, the biggest concern will be heat index values across the region heading into the weekend, with widespread advisory level heat indices (108+) possible starting Thursday and continuing through the weekend as high temperatures in the mid 90s coupled with dewpoints in the mid 70s will lead to these warm conditions. Lows overnight will also be warm in the mid to upper 70s expected across the region.

MARINE.

Tranquil boating conditions are expected to prevail through the week as westerly to southwesterly winds will remain around 10 knots or less through Thursday. Seas are also expected to remain at around 1 foot or less across all waters. Winds will pick up slightly starting Thursday, with sustained values between 10-15 knots expected. Seas are expected to respond with 1-2 foot swells more common. Showers and thunderstorms may briefly bring elevated seas and winds throughout the week.

FIRE WEATHER.

Aside from low dispersions, there are no fire weather concerns expected over the next several days.sion here.

HYDROLOGY.

Localized flooding is possible on Tuesday from the weak low- pressure system mentioned above that is moving from east to west into our region today and tomorrow. A marginal risk (level 1/5) for excessive rainfall exists for the entire region tomorrow in WPC's ERO. Overall, expect widespread totals of around 1 inch; however, isolated higher amounts are possible, especially given that PW values will be over 2 inches across the region. Any flooding is expected to remain localized with locations possibly seeing training storms or getting fast rainfall rates from slow moving storms. In terms of rivers, there are several in action stage, mainly in the Suwannee and Ochlockonee basins, but are forecast to either crest or fall.

SPOTTER INFORMATION STATEMENT.

Spotter activation is not requested. However, spotters are always encouraged to safely report significant weather conditions when they occur (while following all local, state, and CDC guidelines) by calling the office or tweeting us @NWSTallahassee.
