Good Tuesday afternoon! It has turned out to be a fantastic weather day, with low humidity and a refreshing north breeze. Winds have gusted to 25mph in spots today! Dewpoints continue to drop, which will set the stage for record lows tonight. As winds go calm and skies remain clear, temperatures will drop quickly after sunset. Expect temperatures in the upper 70s in some areas by 7pm, then 60s by 10pm. Areas along and north of I-20 stand a good chance of reaching the upper 50s tonight, which is record breaking for most areas. If you live south of I-20, you’ll drop into the lower 60s by sunrise Wednesday morning.
The general trough slowly moves out of the area on Wednesday, but humidity will remain low. Daytime highs will reach the middle 80s on Wednesday, under a mostly sunny sky. Humidity finally starts to make a return on Thursday and Friday, with a risk of a few scattered storms. Highs will remain in the middle to upper 80s Thursday and Friday afternoon. With higher dewpoints, temperatures at night will warm back into the upper 60s.
The risk of a few passing storms will continue through the weekend and early next week, but the risk of rain in one spot isn’t very high. If you have plans outdoors this weekend, have the umbrella handy. Most events will be rain free over the weekend.
The tropics are starting to heat up a bit. We’re watching a large area of low pressure in the central Atlantic, track west. There is a good chance this becomes tropical storm Bertha sometime over the next day or two. Model data is still iffy on the path of the storm, but there is a chance it could impact the lower 48 in 8 to 10 days. There’s still a good chance the storm remains out to sea and never impacts the US. It’s too close of a call for this far out. As you know, a lot can change in that amount of time. Depending on how strong the ridge is to the north of the system, and the position of the trough will determine where this feature tracks. Also, if it rapidly strengthens or remains rather weak will determine the path. If it remains weak longer, it will likely track further west, increasing the risk of a US landfall. If it gets stronger, quicker, it would turn north into a weakness in 5 to 6 days. As I said, there are still a lot of questions that need ironing out. Lets keep an eye on it…
