The strongest storms will be capable of producing gusty winds of 40-50 mph and occasional lightning. Locations that see repeated storms may experience localized flooding. - A high risk of life-threatening rip currents continues at all Central Florida Atlantic beaches today. Stay out of the rough surf!

DISCUSSION

Issued at 155 AM EDT Fri Oct 9 2026

-----------Synoptic Overview-----------

The Florida Peninsula lies between Hurricane Isaias in the Gulf and an H5 anticyclone east of the Bahamas this morning. Southerly mid-level flow is increasing between these two features. The quasi-stationary front that has sat over the state for several days is beginning to migrate northward in tandem with Isaias. By tonight, the front should lift north of I-10 as Isaias makes landfall somewhere near Pensacola or Mobile.

South of the front and across Central Florida, anomalous moisture is expected to remain in place as southeasterly to southerly flow is enhanced. PWATs from 1.8 to 2.5" are forecast through Sunday. H85 temperatures also remain above normal, between +18 and +19 deg C.

Isaias will become an extratropical low over the Tennessee Valley this weekend before drifting into the Mid-Atlantic by early Monday. As the mid-level ridge retrogrades over the Gulf, drier air is forecast to settle toward Florida beginning on Monday. Later next week, global ensembles shift the mid-level ridge axis back toward the state as a trough ejects from the Western U.S. Total moisture should slowly rise to near mid-October norms by the end of next week but remain much lower than what has been in place recently.

-------Sensible Weather & Impacts-------

Through Tonight...

Some modest changes are coming to our weather pattern today. As mentioned in the overview, the stubborn front that has focused rounds of showers and storms will finally lift north of the area. Moisture values also drop off just a bit but remain above normal for the time of year. This will keep at least scattered showers and storms in the forecast (50-60%). However, the loss of deep convergence associated with the front should temper overall coverage compared to yesterday.

REFS members tend to have the greatest coverage of showers and storms this afternoon and evening. With moderate instability and somewhat stronger mid-level flow, a few stronger storms may be capable of producing wind gusts of 40-50 mph. Storm motion looks quicker, which should limit the excessive rain threat. Any localized flooding would be limited to areas that see repeated storms in a short timeframe.

One thing that will be noticeable: it's going to stay very humid. With more sunshine on the way today, the heat and humidity will make their presence felt. Prepare for peak heat indices from the upper 90s to low 100s by afternoon.

Most areas look fairly quiet overnight and into early Saturday morning. A few showers may approach the Treasure Coast before daybreak.

Weekend...

We will keep our direct tap into Caribbean moisture as southerly flow persists through the weekend. Scattered to numerous showers and storms (60-70%) are expected to redevelop in the afternoon hours as the atmosphere destabilizes. We will continue to monitor locations that are already saturated for potential flooding. The storms will move fairly quickly from south to north, with locally gusty winds of 40-50 mph still expected in the strongest storms. Winds should turn southeasterly and become breezy on Saturday.

Warm and humid weather will persist, with highs in the mid/upper 80s and peak heat indices in the upper 90s to around 105 degrees.

Next Week...

A weak front is expected to settle through Central Florida on Monday. This feature should bring modified continental air southward, ushering in an end to this unsettled weather pattern. Guidance suggests that dew points may dip into the 60s as early as Monday afternoon. Drier-than-normal total moisture is then forecast to stay overhead through at least Wednesday, with slow moistening late in the work week.

Mostly dry conditions are forecast, with cooler morning lows in the mid 60s to low 70s transitioning to warm afternoons well into the 80s to near 90.

MARINE

Issued at 155 AM EDT Fri Oct 9 2026

Hurricane Isaias will reach the northern Gulf later today and make landfall somewhere near Pensacola, Florida, by tonight. Locally, this will act to lift a front north of the local Atlantic waters. Moderate winds turn southeasterly today and Saturday before becoming southerly on Sunday. Small craft should exercise caution at times, particularly on Saturday. Scattered to numerous showers and storms will continue through the weekend. A front arrives on Monday, ushering in drier air next week.

SE winds 10-15 kt today, increasing to 15-20 kt on Saturday. Winds turn southerly on Sunday at 10-15 kt. Seas generally 3 to 4 feet through this weekend. A front will turn winds northwesterly on Monday, with seas remaining 3 to 4 feet.

AVIATION

(12Z TAFs) Issued at 645 AM EDT Fri Oct 9 2026

A weak frontal boundary will lift north of the area today. Ocnl MVFR CIGs this morning along the front esp northern terminals and patchy MVFR fog across the southern terminals. Winds will become SE later this morning and thru the afternoon with speeds 7-12 knots with gusts up to 20 knots esp coastal terminals. SCT- NMRS SHRA/TSRA will develop during the aftn lifting N/NE, focusing on inland (MCO) and northern terminals. So late aftn TEMPOs look good there. Less coverage south of MLB where PROB30 or simply VC term is used.
