Good morning bloggers,
Today is the 7th day of the first heat wave of the summer. The next chance of rain is barely showing up for early next week and confidence is quite low at this time. We have a slight chance of thunderstorms on our 7 day for late Sunday into Monday. The latest computer models have very little rain in our area as a very weak cold front will move into our region by Monday and then it is forecast to fall apart south of us around a week from today, leaving it dry and slightly cooler for the Major League Baseball All Star Game one week from tonight.

This map shows the 500 mb flow (18,000 feet up) valid at 7 PM this evening. The main jet stream has weakened into it’s summer position way up to the north dipping south over the Pacific Northwest. This allows the room for the anticyclone to expand north into and over the plains states this week and we will likely see near 100 degree heat every day between now and Sunday. The weather pattern will become more favorable for a weak front to get into the area by early next week, and a likely stronger cold front a few days to a week later. But, this part of the pattern that is creating the conditions for this heat wave will be due to return in August.
Have a great day. We will be preparing some special weather graphics to describe this developing and shifting weather pattern.
