By the beginning of the long term, the cold front will be through the area with associated precipitation coming to an end. The front will then become quasi stationary over the gulf. A surface high pressure will be building in over the southern plains and it will quickly make its way to the east. This will allow winds to again whip around out of the south by the end of the weekend. By late Sunday into Monday the stalled out front will make its way north back through the area. This will serve as the next bringer of rain for us, however Probability of Precipitation are scattered at best. Past that point the models have not come to an agreement on the next front. The EURO places an upper level low over the central plains with a front expected to enter the CWA (County Warning Area) by late Tuesday while the GFS (Global Forecast System) is nearly 24h delayed. Ran with the NBM which gave an isolated chance of precipitation near the end of the long term.
Temperatures will be near 5 to 10 degrees above normal in the low to mid 80s for the first few days of the long term despite the cold front. Lows will be in the 50s to 60s. The only respite will come in the form of drier air / reduced dewpoints in the 50s to 60s. However as mentioned before, southerly flow will reintroduce itself as the surface high departs and the warm front treks north. Temps and Td will both be on the rise. By Monday (and the rest of the long term) we will be looking at max temps in the mid to upper 80, with some areas flirting with the low 90s. Lows will be as warm as the low to mid 70s with matching dewpoints.

Light rain showers continue to spread across the coastal waters this morning with a rumble of thunder possible after daybreak. Most showers should end from west to east during the afternoon. Moderate offshore flow and higher seas will prevail through today. The Small Craft Adv and Exercise Caution will expire later this morning.
As the surface high moves east on Thursday, expect onshore flow to resume. A significant storm system in the Midwest will increase the pressure gradient Friday, resulting in increased winds and seas. Another Small Craft Adv will be likely.
