TROPICS: In the Gulf, we have a weak tropical wave that is generating scattered storms just offshore. This should be bringing excessive rainfall to Southeast Texas over the coming days, on the order of 6 to 10 inches of it in the Houston metro area. We will NOT be impacted by this in Central Alabama.
Off the Atlantic coast, we have what is now Hurricane Humberto. This storm has strengthened at a decent rate, but is luckily tracking East, away from the shore. It will be bringing NO impacts to the United States, tracking out into open waters over the coming days.
The next tropical wave we’re watching is located in the main development region of the Central Atlantic, at about 40°W longitude. It has a good chance of developing into a depression OR tropical storm over the next 2 days. If it becomes a storm, it would be called Tropical Storm Imelda. Because of how far away it is, it’s not something we’re concerned with for the immediate future. Just something we’re watching!
TUESDAY-WEDNESDAY: Not much will change with our current pattern for Tuesday & Wednesday. The above-average heat will hold across Central Alabama. That means highs consistently in the upper 90s, along with abundant sunshine. NO chance of rain.
THURSDAY: Some changes are in store beginning on Thursday. A cooler, drier airmass will begin to move in from the East, as opposed to the West, which is generally where our cold fronts originate. This will occur thanks to an area of high pressure centered over the Ohio River Valley. This airmass will also be funneled Southward into Alabama by the Appalachian Mountains, in a phenomenon known as “cold-air damming”.
Long story short, Thursday afternoon is when the *wild* heat comes to an end. Highs will drop to the low 90s Thursday afternoon. Partly cloudy skies and a 20% chance of showers as we switch between airmasses.
FRIDAY: The crisp, autumn-like air will fully move in Friday morning. Expect it to actually FEEL like fall outside Friday morning! Temperatures should drop to the low 60s close to sunrise. Highs in the afternoon will still be warm, but a little more comfortable in the mid & upper 80s.
THIS WEEKEND: The taste of fall will be brief. Lows in the morning will be mild in the mid 60s, but we’ll be back to close to 90° this weekend. No chances of rain to worry about for this weekend either…sunshine keeps on coming for Saturday and Sunday.
