.Near Term [Through Today]... The large scale pattern is marked by near zonal flow. At surface...strong high off mid-Atlc with ridging Swwd across Gulf region. Locally this translates to Sly flow at lowest levels with SW then WLY flow above. With veering flow contributing to more humid conditions (24 hr dew point comparisons show local airmass 2 (east) to 10 (west) degrees higher). RAP13 soundings reflect this with PWATS inching up to around 0.8 inches this afternoon. Very weak local gradient will allow development of seabreeze which will bring some afternoon Cu clouds inland and...with cool shelf waters...temper coastal temperatures a few degrees. Expect highs from around 75 at the coast to 80 elsewhere. .Short Term [Tonight Through Sunday]... High pressure will remain centered near or just east of the region throughout the short term period. This will result in a period of dry and warm conditions with temperatures near to slightly above average. The model guidance does show a sea breeze developing along the coast each afternoon, which will likely result in temperatures near the beaches being a few degrees cooler in the afternoon given how cool the shelf waters remain. .Long Term [Sunday Night Through Thursday]... The primary focus in the long term period will be on an approaching storm system in the Monday through Tuesday Evening time frame. While the models are reasonably synced on the timing of this system bringing the bulk of the rain through on Monday afternoon and overnight, there are subtle differences with respect to the intensity of the system. Most of the models prefer a weaker solution with a cold front coming through early Tuesday morning with little prospect for severe weather or widespread heavy rain. The Euro tries to develop a more potent wave in the southern stream, resulting in a stronger system. For now, have kept the system more progressive and weaker. In any event, should be a good rain producer with 1 to 1.5 inches possible. Thereafter, drier and cooler conditions return for the remainder of the period. .Marine... High pressure will remain in place across the marine area throughout much of the weekend. By Sunday, as high pressure moves into the Western Atlantic, the tightening gradient between this high and an approaching storm system will result in increasing winds and seas by the first of the week. .Fire Weather... Light onshore flow through Sunday will allow enough low-level moisture to keep minimum humidity values above critical levels. The airmass will noticeably moisten up on Monday with the next weather system. No red flag concerns are expected thru that time. .Hydrology... Nearly all of the rivers across the northern portion of our area have crested and continue to fall. Rises are still occurring farther to the south across portions of the lower Choctawhatchee River, Apalachicola River, Flint River, Ochlockonee River, and Steinhatchee River. The next chance of rainfall is on Monday into Tuesday. The system currently appears progressive enough to prevent excessive rainfall, but rainfall amounts may be enough to temporarily halt some of the river falls.
