.NEAR TERM [Through Friday]... A plume of tropical moisture is present across the southeast big bend with precipitable water values rising to near 2 inches today in that region. As a result, the coverage of showers and thunderstorms will be highest in the southeast big bend for the remainder of the afternoon. Elsewhere, below average deep moisture is expected to limit convective coverage into the 20-30% range over most of the rest of the area through early this evening. Overnight lows will generally be in the low to mid 70s.

For Friday, very weak upper level troughing will persist over the western portions of the area with weak southerly flow across the area. The very dry mid and upper level airmass that has been over the region for the past few days will gradually start to erode with increasing precipitable water values. Thus, a slight increase in convective coverage is expected for Friday afternoon across the area with Probability of Precipitation ticking upwards into the 30-50% range over most of the area compared to the 20-30% over the past few days. Afternoon highs will generally be in the low 90s near the coast to mid 90s inland.

.SHORT TERM [Friday Night Through Sunday]... Upper level ridging noses over the state from the east through the short term, causing forecast high temperatures to climb into the mid to upper 90s across much of the area. A plume of deeper moisture currently over the peninsula will also edge closer, leading to an increase in moisture through the short term. Even with ridging overhead, the abundant moisture will still keep some isolated to scattered showers and thunderstorms possible both Saturday and Sunday afternoons, with the greater coverage expected over the eastern Big Bend region and closer to the deeper moisture.

.LONG TERM [Sunday Night Through Thursday]... Heading into the work week, the ridging over the state begins to weaken and retreat eastward as a series of impulses move across the eastern CONUS. While our area will remain in fairly zonal flow with ample moisture still in place, a return to a more seasonable pattern of scattered to widespread afternoon showers and thunderstorms is expected. High temperatures will also trend back towards the low to mid 90s by midweek.

Marine
Light southwesterly winds and low seas will make for favorable boating conditions over the next several days outside of thunderstorms.

Fire Weather
Hazardous fire weather conditions are not expected over the next several days.

Hydrology
Typical summertime convection is expected to bring periods of showers and thunderstorms across our area, but Quantitative Precipitation Forecast yields 7-day totals of generally 1 to 2 inches or less. Isolated higher amounts are always possible where precipitation persists for long durations. There are currently no flood concerns, and all local rivers and creeks are in good shape.
