SHORT TERM
(Today through Saturday)
Issued at 314 AM EDT Fri Mar 29 2024
High pressure and dry conditions are anticipated through the short term period. Skies will be mostly clear with some passing thin high clouds. Winds will be light northwesterly for today, then switching to the southwest tonight. The upper levels will remain quiet also.
NW flow aloft will persist today and tonight and turn more zonal on Saturday. Temperatures will be near or just slightly above normal.

LONG TERM
(Saturday night through Thursday)
Issued at 314 AM EDT Fri Mar 29 2024
Starting off the long term outlook on Saturday morning, broad upper level ridging and a robust sfc high off the east FL coast will mean clear and dry conditions through Monday evening. Southwest flow on the northwest side of the sfc high will mean warm and moist air is dragged out of the GoM. Highs through Sunday and Monday will be in the upper 70s to low 80s, a bit above normal for this time of the year. Given the low PoPs throughout the period fire wx could become a hazard, however moisture advection should bring our minimum RH values above 25 percent Sunday and Monday.
Moving into early next week, a deep and positively tilted trough will make its way eastward out of the western CONUS. A CO sfc low will also move ENE, however current model guidance shows uncertainty in the forward progression of the system as a whole. The GEFS in particular has several members actually cutting off the bottom of the trough and losing some of its dynamic energy, which would have significant downstream forecast impacts. PoPs for our area begin to increase across the NW CWA late Monday night into early Tuesday morning within the warm sector. However the main action will likely not begin until closer to Tuesday afternoon and Tuesday night.
Convective activity will be heavily controlled by the forward movement of the impinging front and CAPE. Current model blend guidance indicates a 90% CAPE of around 900 J/Kg, however this is countered by a 10% CAPE of <50J/Kg. Shear should not be a limiting factor in this case with model consensus of at least 50Kt of bulk shear. Similarly, analogous scenarios indicated by CIPS suggests some likelihood of sever potential. However, given recent trends of prefrontal precipitation ahead of slow/stalling frontal systems, it will probably be best to remain conservative of any potential hazards. Will continue to monitor conditions while maintaining a forecast for scattered thunderstorms with the potential for a few storms to become strong.
QPF from this system could become locally heavy. PWATs >1.5" and a slowing front will mean training could become possible. Continued monitoring of frontal development will remain necessary.
Conditions dry and clear out with the frontal passage next week.
Windy post frontal conditions and dry air may mean Fire WX becomes a concern once again.
