632pm CDT Thu April 16 2026

(This evening through next Wednesday) Issued at 1255pm CDT Thu April 16 2026

Surface high pressure centered across the western Atlantic and extending into the central gulf continues to maintain a warm, tropical airmass this afternoon. Meanwhile, ridging aloft extending across much of the gulf is keeping a cap on most precipitation. Radar analysis this afternoon does show a few areas of drizzle developing, but this is not expected to intensify into anything significant. Persistence forecasting will prevail Friday and into Saturday with little day to day change in sensible weather.

An upper level low moving across southern Canada will push a seasonally strong cold front across the eastern CONUS and through the gulf coast Saturday evening through Sunday morning. Deep moisture ahead of the front will support high rainfall rates in thunderstorms along and ahead of the boundary and WPC has maintained it's marginal risk of excessive rainfall for nearly the entire region. Storms and the frontal boundary are expected to move pretty quickly across the region so despite the high rainfall rates, forecast Quantitative Precipitation Forecast continues to remain consistently in the quarter to three quarter inch range.

Breezy northerly winds will develop in the wake of the front Sunday morning advecting noticeably cooler, drier air into the region through the day. Monday morning will be the coolest day of the week with temperatures falling into the upper 40s to lower 50s. High pressure will slide east of the area by Tuesday afternoon turning winds back out of the southeast initializing a gradual warming trend Wednesday through the end of the week.

Breezy onshore winds between 10-15 knots will persist today through Saturday afternoon with seas ranging from 1-3 feet. A cold front will move through the coastal waters Saturday night into Sunday morning accompanied by showers and thunderstorms. Strong offshore winds will develop behind the front Sunday morning with gusts up to 35 knots possible. A Small Craft Advisory will likely be needed Sunday and Monday and a Gale Watch/warning may be required Sunday morning. Winds will diminish Monday afternoon before turning back onshore Tuesday afternoon where they will remain through the rest of the week.

Fire Weather
Issued at 1255pm CDT Thu April 16 2026

Steady southerly winds will prevail this afternoon through Saturday maintaining a warm, tropical airmass across the region. A few areas of drizzle may develop each afternoon, but these will be sporadic and short lived. Patchy ground fog will have the potential to develop late tonight into early Friday morning. Any fog that develops will dissipate by 9 AM. A cold front will push through the region Saturday night into early Sunday accompanied by showers and thunderstorms that will be capable of producing heavy rainfall. Strong northerly winds will develop Sunday in the wake of the cold front. Additionally, much drier air advecting into the region will drop minimum RH values into the mid 20s to mid 30s Sunday and Monday afternoon. This will have the potential to create dangerous fire weather conditions both Sunday and Monday afternoons. Winds will turn back out of the southeast by Tuesday afternoon with dewpoints increasing through the remainder of the week.
