.DISCUSSION...
Issued at 234 AM EDT Thu Apr 3 2025

Deep meridonal upper trough through the wrn US accentuated by 120+
knot upper jet streak will continue to dig south twd the US/Mexico
border through late Fri. This deep sys ejects out in west TX Sat and
accelerates newd through the OH valley late Sun. Composite outflow
reinforced cold front early this morning will stall out over the mid
MS valley today before retreating back north Fri in response to
upstream sfc wave development. This yields and increasing warm
advective pattern developing late Fri and again late Sat with
potential for two additional rounds of heavy rainfall in some areas.
Best model consensus is across southern zones and will hold with
areal extent of prior issued long duration flood watch yet
acknowledge potential exists for some nwwd creep in frontal
zone in later model runs.

In wake of this sys, sharp ern Canada upper trough dvlps/deepens
with at least 2 shortwaves progged to drop through the lakes, one
late Mon and the other toward Thu. Unseasonably cold temps Sun-Tue
will claw their way back up late next week.

.AVIATION /06Z TAFS THROUGH 06Z FRIDAY/...
Issued at 150 AM EDT Thu Apr 3 2025

VFR conditions should settle in for both sites through the
period as drier air works in. Small T/Td spreads would have
resulted in some fog issues with the clearing, but given the
strong winds still in place suspect we will be fine (may have to
watch for stratus development). Winds will diminish after 00Z
with fog maybe becoming more of an issue outside this period.
