Cooler Weather Finally Poised To Come Next Weekend!

Temperatures Next Weekend based off of the “GFS” model

Yes folks you read the title right, cooler, and I mean much cooler weather is headed for the eastern half of the nation. What will happen over the next few days is that we will start to see the cooler air from Canada, spilling into the Midwest and moving east towards the northeast by late week. This is only a sign of things to come I believe. While this will be a short lived cool spell lasting Saturday through Monday, later on the following week models are pointing at another cool blast of air coming from Canada.

The best day’s will be Sunday and Monday. If you have been craving to open up your windows to cool crisp air, with no humidity that will be the day to do it. The front will produce some showers and Thunderstorms in the Mid-Atlantic and northeast but they don’t appear at this time like the will be severe. But this cool blast is most welcome and is the beginning of what I think is a pattern change. I will have more details as the week comes along!

This cool shot of air is going to wake up the hurricane season starting around the 20th. The cooler air will raise pressures over the United Stated, and force some convergence in the Gulf of Mexico and Caribbean. Combine that with an upward MJO pulse, and we could see things really start to crank up. Need to watch ex TD 7, could be a problem for the western Gulf next week.

Well Brad, I’m glad you agree with me. Ex-TD 7 needs to gain a little latitude if it wants to develop, the main vorticity appears like it may interact with central America. 93L looks like it may become a tropical storm before exiting into the north Atlantic, conditions are much more favorable now that it is further west. This will be the main theme this year, tropical waves move off Africa, and stay weak until they get further west where their is more moist air, slower trade winds, higher SST, and TCHP values. This is something Joe Bastardi and others have been touting since spring, and of course a pattern like this leaves the US coast very vulnerable to hurricane strikes because when these storms develop further west they have a much greater chance of hitting land than systems that form out near Africa in la nina and active cape verde years.

The northern part of Ex TD 7 should survive the trek over the yucatan, and if it does make it into the Gulf it will encounter a favorable environment, with a broad trough over the central-eastern Gulf of Mexico, this will allow for favorable ridging to develop over the western Gulf. The GFS model has been consistent for run after run showing development, however other models are struggling to show it, and it is probably because the the MJO is coming around, and that will enhance the monsoon low and it’s possible that many models are having problems resolving the small-scale pattern, and the monsoon low over central america may be overshadowing their solutions. Regardless looks like something will attempt to develop over the western Gulf starting by Friday and the weekend. The exact location it will affect appears uncertain and it will all depend on how strong the system gets, the stronger it gets generally the farther north in latitude.
