8/23 – Rob Knight’s “Tropical Moisture” Morning Forecast
Satellite imagery shows increasing bulk tropical moisture in the west-central Gulf of Mexico. This will be steadily advancing northward and bring moisture values upward into the 2/3 inch range today, with these conditions expected to linger through the weekend. Temperatures should be held to slightly below normal during the daytime due to rain and extensive cloud cover though a brief sprint to max temps in the late morning hours before t-storms gets going.
The upper pattern will transition into next week. It appears some semblance of a front, or at least, some continental influenced airmass to bring some mid-level drying to bring a return to near normal rain chances and a trend to slightly above normal temperatures as surface high pressure builds from the west and northwest by middle of next week. Meanwhile, in the gulf, the models are hinting at a tropical wave to traverse the central gulf heading into next week.
