Latest water vapor imagery shows well defined upper low in the NE Gulf of Mexico continuing to move east across North Florida this afternoon. Continued isentropic lift across the area is bringing areas of rain and rainshowers, mainly north of I-40 across the area. Expect this activity to begin to taper early this afternoon, although we will likely see spotty pcpn area wide persist into this evening before ending. Had to adjust temperatures downward area wide as pcpn and cloud cover have caused temperatures to level off after sunrise this morning. Similarly lowered afternoon high temperatures as any subsequent heating will struggle to get temperature increases of 10 degrees in continued cloud cover and areas of pcpn. Otherwise no changes to fcst for this afternoon.
