Area Forecast Discussion|
National Weather Service Tallahassee FL
1122am EST Wednesday Jan 29 2020
Only minor changes were made to the forecast this morning to reflect current temperature trends and rain chances. Rain is already beginning to wall across our western zones with these chances spreading east through the remainder of the day. The quick moving nature of this weather system will have us see rain chances quickly move out of the area by later this evening.
Near Term - Through Today
A shortwave and accompanying surface low will move into the Southeast through the day today. The surface low will drift south into the Gulf towards a more unstable airmass, while the shortwave continues through the continental Southeast. Deep layer isentropic ascent from the surface (offshore) through about 8kft (inland) will result in a large rain shield traversing the region from mid-morning through the evening. Rainfall amounts will generally remain below a quarter of an inch, with the heaviest amounts closer to the surface based storms well offshore.
Highs will be capped in the 50s in locations where the rain arrives earliest, and should reach the low to mid 60s towards the Suwannee Valley region.
Short Term - Tonight Through Friday
A progressive pattern will remain in place this period as our area is on the backside of the departing low pressure system tonight. High pressure will quickly build in with zonal flow aloft. This high pressure will be shortlived as the next low pressure system moves into the area Friday. Showers will begin to affect our western areas Thursday night then overspread the area Friday. It appears the rainfall will more more abundant and widespread Friday as compared to today but rainfall amounts with both these systems will average around an inch. Highs will remain mild with readings in the 60s, a little cooler Friday as more clouds and rainfall is expected.
.LONG TERM [Friday Night Through Wednesday]... Light rain will linger into Friday night as the low pressure area departs the region. Some clouds will remain into Saturday and isolated showers could occur Sunday in association with the upper low as it moves by as well. Then high pressure and ridging build in late Sunday into Monday with a period of dry conditions. Even that is shortlived as the next frontal system brings a chance for rainfall Tuesday and Wednesday. Highs in the 60s this weekend will warm into the 70s for the start of the next work week.Lows in the 40s this weekend will warm to the 50s by Tuesday morning.
