Area Forecast Discussion
National Weather Service Birmingham AL
323 PM CDT Tue Mar 24 2020

.SHORT TERM...
/Updated at 0237 PM CDT Tue Mar 24 2020/

This afternoon through Wednesday.

Ingredients are coming together for a very active period of severe
weather this evening for areas along and north of I-20. The airmass
across central Alabama has been baking under a warm low level
southwest flow all day with temperatures reaching the upper 70s to
lower 80s. Despite heating, surface dewpoints been steady in the
lower to middle 60s throughout the day, indicating a fairly deep
moist layer near the surface. 12Z JAN/BMX soundings show capping
inversion just below 700mb, which has kept a lid on convection
through the early afternoon. Latest radar scans show convection
breaking out over northern MS where surface based CAPE was near
1500 J/kg. Becoming increasingly concerned about tornado potential
over northwest counties of central Alabama. Hi-res models are
showing more discrete supercell development over northeast MS
later this afternoon. Forecast 0-3km EHI values across the
northwest counties are also increasing with current runs of the
HRRR model. The discrete cells should organize into a broken line
of storms by 9 or 10 pm with a lower threat of tornadoes, but
still showing rotating cells within the line. Extended severe
threat until midnight due to the threat of ongoing severe storms
across east Alabama. Everything should be winding down quickly by
midnight as low level flow weakens veers and weakens.

The remaining showers and thunderstorms should exit east Alabama
by sunrise Wednesday. Decreasing clouds and slightly cooler
temperatures on Wednesday with highs ranging from the lower 70s
north to lower 80s south.

58/rose

.LONG TERM...
/Updated at 0350 AM CDT Tue Mar 24 2020/

Wednesday night through Monday.

Post-frontal, dry conditions will be in place across the Southeast
Wednesday night as the surface low moves eastward into the Atlantic
while the east to west oriented cold front continues southward
through the Florida Peninsula. Weak, cool air advection and
northwesterly flow will allow temperatures to decrease into the
upper 40s northeast and 50s elsewhere on Thursday morning before
rising sharply after sunrise as a 593dam ridge builds over the Gulf
of Mexico. A surface high will develop over the Mid-Atlantic and may
produce weak cool air damming over northern parts of Georgia which
would keep temps a few degrees cooler across our northeast.
Nonetheless, height rises, warm southwesterly low-level flow, and
dry, subsident air will accompany this setup, allowing for afternoon
highs around 15 degrees above average for this time of the year with
temps topping out in the 80s area-wide on Thursday and Friday.
This occurrence would challenge a few of our daily high records
for both days.

Meanwhile, an upper low over the Central US will track towards the
Great Lakes Region on Saturday with a surface front reaching the
Lower Mississippi Valley early Saturday afternoon. Guidance has
trended towards better agreement in a late Saturday frontal passage
across the forecast area, so PoPs were raised during this time frame
with early evening thunderstorms possible before instability wanes
after dark. There are still some uncertainties with this system, but
severe weather is not expected at this time. Cooler temperatures
and a short break in the rain are expected behind the front for
the start of next week, but guidance indicates another system will
approach the area beyond this period.

.AVIATION...
18Z TAF Discussion.

A capping inversion will keep a lid on convection thru 00z across
central Alabama. Warm low level conditions will produce sct-bkn
afternoon cumulus with bases 4-5k feet agl. A deepening sfc low
over Arkansas will create a tight sfc pressure gradient over
Alabama with southwest winds 10-12 kts with gusts to 20kt thru
02z. Sfc winds will veer to a more westerly direction overnight
and weaken as rain cooled air moves over north Alabama. Clusters
of storms will develop over northern MS by mid afternoon and
spread into west Alabama by 23z. High instability and shear will
create favorable conds for severe storms across north Alabama
between 23z and 05z, impacting all northern TAF sites. The storms
will eventually form into a line of storms that will impact KMGM
by 05z. but probably in a weakening phase. Cigs will lower
overnight as cooler air moves southward behind cold front.
Widespread MVFR cigs expected after 08z, with lcl IFR cigs.

.FIRE WEATHER...

Scattered to numerous showers and thunderstorms will spread across
north Alabama tonight. Some of the storms could be severe, mainly
along and north of I-20. A weakening band of showers and storms
will push into the southern counties after midnight. A weak cool
front will bring drier and slightly cooler air into central
Alabama on Wednesday. Warmer conditions on Thursday and Friday
with no rain expected. Despite highs in the 80s Thursday and
Friday, afternoon humidity levels will only fall into the 40-50
percent range.
