Good Tuesday bloggers,
We tied the record low this morning, 57°. Record cold in July is a good thing. That means you are having a refreshing break from the heat and humidity. The average low is 69°.
WEDNESDAY MORNING: The surface low that is over northern Kansas today will be on the Iowa-Missouri border Wednesday morning. This puts our area in a good location to have a clear sky and almost no wind which maximizes cooling. The record low is 57° again, set in 2004. We will come close or tie the record again.
WEDNESDAY AFTERNOON: The entire USA is getting a break from the heat except for the southwest deserts and a few locations in the Rockies. Heat in the southwest deserts in July, not too unusual. We will see a high in the low 80s along with low humidity as the surface high pressure drifts away.
We are tracking two systems Thursday-Monday that will emerge out of the summer monsoon. The pattern is one in which there is an upper level high over the southwest USA with monsoon moisture and disturbances rotating around it. A few of these disturbances get caught up in the flow and track east and southeast across the Plains and Midwest.
THURSDAY: The disturbance on Thursday will come right over the area with clouds and possibly some sprinkles or a brief shower. It is this low humidity we are enjoying that is preventing this system from producing rain and thunderstorms. Highs will be in the upper 70s to low 80s due to the clouds.
The next disturbance comes in Sunday night-Monday and this one will have adequate moisture to generate rain and thunderstorms. There will be 1-2 more rain and thunderstorm chances next week as a cold front or two drop into area along with monsoon disturbances.
Have a great rest of your Tuesday and week ahead.
