We are moving through mid-September, and it’s becoming more noticeable that Autumn is starting to take over for Summer in terms of the weather patterns. Weather systems are beginning to become stronger and more organized than they tend to be during the Summer, cold fronts are now moving across the country more frequently, and as a result temperatures are taking bigger drops in much of the country as each front passes by.

For instance, a strong weather system with an associated cold front will be moving across the Midwest, Great Lakes, Northeast, and Southeast the first few days of this week.  It will be bringing widespread showers and T-storms, some heavy rain, and possibly even some severe weather in the form of strong winds. In its wake, a couple days of very cool weather will follow, with below normal temperatures likely in each of these regions. Meanwhile on the flip side, it will be warm to hot out west, as the region sees little to no precipitation this week.

Also, we are more than half way through the hurricane season, and there are currently no tropical systems either active or expected that would pose any threat to Southwest or Air Tran.

Here are this week’s weather highlights:

  • For the Northeast, it looks to be an active day on Tuesday, with numerous showers and some T-storms expected, possibly containing strong and gusty winds. Heavy rain also is a good bet up and down the Eastern Seaboard on Tuesday, possibly into the first half of Wednesday (BWI, PHL, EWR, LGA, DCA, IAD, ISP, BOS, BDL, MHT, PVD).
  • The earlier-mentioned cold front will move through the Midwest, Great Lakes, and Ohio Valley from Monday afternoon through Tuesday evening, with showers and some scattered T-storms possible along and ahead of the front. Locations in these regions, including MDW, will likely receive some impacts as the system moves through (MDW, MKE, MCI, DSM, STL, IND, SDF, CLE, CAK, CMH, DAY, GRR, FNT, DTW, PIT, BUF, ROC). Another round of much cooler temps will then follow.
  • A soaking rain event across the Southeast, mostly on Monday and Tuesday, with numerous showers and T-storms across the area (ATL, BHM, BNA, MEM, LIT, MSY, JAN, GSP, CLT, CHS). Once the system exits the region, it looks much more quiet the second half of the week.
  • In the West, a warm and dry week ahead, with little to no precipitation expected, and very warm temperatures, including at LAS, PHX, and DEN.
  • The week looks mostly dry and mild across Texas as well, with very little chance for any precipitation, including at HOU, AUS, SAT, and DAL.
Have a fantastic week!
