Update
Updated for morning discussion.

Discussion
High pressure at the surface remains wedged into the forecast
area from the north, with continued west northwest flow aloft.

Quiet weather will continue across the region today, but some high
clouds will remain overhead as a mid upper level distubance
gradually shifts east across the gulf of mexico. Look for highs
today to range from the lower to upper 60s, with northeast winds
generally between 5-10 mph.

The current forecast is in good shape. I'll make a few adjustments
to hourly elements of the forecast to account for current trends.

Otherwise, no major changes will be made on this update. 19
prior discussion below:
today and tonight...

after a chilly start, it will be a rather pleasant late march day
across the arklamiss region. Upper troughing that has been over the
area this weekend will move east and upper ridging will begin to
move in. Highs today will be in the lower 60s across the north to
the mid and upper 60s across the central and southern part of the
forecast area. With mostly clear skies tonight and light winds,
another chilly night is expected. The coldest weather will be in the
northeast part of the forecast area, where readings will be in the
mid and upper 30s. The rest of the area should reach into the lower
40s. 28
Tuesday through Friday: benign weather conditions will prevail
through the majority of the week, as the upper jet stream generally
remains displaced far enough south to keep our region in a dry and
stable airmass.

Though weak cold advection will persist into Tuesday, mostly sunny
conditions and low dewpoints should still favor decent daytime
heating, with temps in the 60s. Temps will then trend upward
Wednesday as surface flow becomes more southerly ahead of an
approaching mid level shortwave. This wave will swing across the
midsouth late Wednesday, bringing a weak surface trough through our
area with just enough moisture recovery for a chance of showers
mainly over the northern half of the area during the evening and
overnight. Dry conditions look to return by Thursday, and as low mid
level heights quickly recover behind the system, temps will resume a
slow upward trend through the end of the work week.

This weekend: a mid upper trough will begin to take shape over the
western CONUS toward the end of the week, lunging slowly eastward
into the weekend. This system will likely be the next instigator of
rain chances for our region, but given the somewhat disorganized
representation of this system in the guidance, timing details remain
unclear. For now, Saturday looks mostly dry, with rain chances
trending up Sunday or Monday. Dl

Aviation
12z TAF discussion:
vfr conditions will prevail today. Winds will be out of the north-
northeast around 5-10kts. Winds will go light to calm overnight
tonight. No aviation concerns expected. 28
