UPDATE
Issued at 918 AM EDT Wed Jun 18 2025
It is a pretty quiet morning across West Central and SWFL this morning as some thunderstorms continue off the FL West Coast. When compared to this time yesterday, the atmosphere has become more saturated, with the PWAT increasing from 1.33 yesterday to 1.90 this morning. While some of this is likely residual from the late thunderstorm activity, the overall expectation is that the atmosphere will become more saturated through a deeper layer over the next day or so, leading to an increase in convective activity as this occurs.
However, the impact is favored to be more muted for today. As such, the overall expectation is for a very similar day to yesterday: warm, humid morning, a hot afternoon, and late storms once again.
Overall, this is consistent with the current forecast.
DISCUSSION
Issued at 322 AM EDT Wed Jun 18 2025
Overnight showers continues this time over Tampa and St. Pete. These showers should start to dissipate in the next couple of hours.
The trend we have seen the last couple of days will continue through the work week with southeasterly flow in place but drier air aloft limiting activity for most of the day. The storms that due develop will mainly be on the west coast of Florida in the late evening and early overnight hours.
As we go into the weekend and early next week ridging will shift slightly giving us more of a northeasterly flow. This regime typical favors shower chances in Southwest Florida. The drier air aloft looks to stick around for the weekend however the moisture returns by early next week which will bring shower chances back up again.
AVIATION
(12Z TAFS)
Issued at 918 AM EDT Wed Jun 18 2025
Thunderstorms remain the primary impact, but once again look to be delayed until late in the evening and overnight as drier air and light ESE flow delays convective initiation. Moisture is expected to increase over the next day, so earlier and more extensive thunderstorm impacts begin returning tomorrow and last through the remainder of the week.
MARINE
Issued at 918 AM EDT Wed Jun 18 2025
An ESE flow remains in place across the region, with increasing moisture favoring increasing rain chances for late week.
