DISCUSSION
Issued at 240 PM EDT Mon Oct 12 2026

Currently-Tonight... KMLB radar imagery shows dry weather across east central Florida. GOES-19 satellite imagery and local observations indicate clear skies over the region. Analysis charts show the cold front that moved through yesterday and last night to the southeast of east central Florida. Building high pressure (~1022mb) is situated over the Deep South. Temperatures have cooled behind the cold front and are currently in the low to mid 80s with dew points in the low 60s to low 70s. Winds have been somewhat breezy at times and are currently from the north at 6-12mph with gusts to 15-22mph.

Dry weather is expected to persist for the remainder of today and tonight as high pressure builds over the Deep South. Expect low temperatures in the low 60s to low 70s tonight (warmest along the coast) with clear skies.

Tuesday-Wednesday... The dry weather will continue on Tuesday before moisture begins to increase over east central Florida as northerly flow veers onshore. A longwave ridge is expected to build over the eastern CONUS through the forecast period. At the surface, high pressure (~1020mb) is expected to build over the southeastern US through midweek. Guidance shows PWAT values increasing to 1.0- 1.3" by Wednesday. Isolated onshore moving showers are forecast on Wednesday (mainly to the east and south of the Orlando metro. The potential exists for isolated gusty showers with moderate rainfall. Seasonable afternoon highs in the mid to upper 80s with seasonable to above normal (~1F-3F+ degrees)
low temperatures.

Thursday-Sunday... Deterministic models have come into slightly better agreement on the mid to long term forecast, however, there are still deviations in the different LREF-clusters' potential model solutions Friday and into the weekend. A longwave ridge is forecast to build over the southeastern US on Thursday with the apex of the ridge forecast to reach Canada. At the surface, the high is forecast to shift east over the southeastern US and the southwest Atlantic Friday into Saturday. There still remains uncertainty in the strength of the mid/upper level trough/low that is forecast to deepen over the eastern CONUS Friday into Saturday with the LREF-clusters showing clusters that have the trough deepen all the way to the Deep south and the other clusters deepening the trough to the Tennessee Valley, as well as the Carolinas. At the surface, a cold front is forecast to extend from low pressure over the northeastern US and move east-southeast across east central Florida Friday into Saturday. Rain chances increase most days through the forecast period with isolated to numerous showers (mainly south of Cape Canaveral on Thursday) and isolated to widely scattered lighting storms forecast each day.
Winds are forecast to become breezy to windy from the northeast Saturday and Sunday. The probability of wind gusts to 35mph or greater is at 30-70%+ on Saturday (highest probabilities north of the Treasure Coast) and 40-80%+ on Sunday. Seasonable to above normal temperatures on Thursday and Friday are forecast to cool into the weekend behind the cold front.
