THIS WEEK

High pressure builds across northwest Missouri on Monday, causing the winds to flow from the northeast. This flow is a dry one and typically results in cooler than normal readings. Temperatures will once again be below normal with highs in the lower to middle 80s. The unseasonably cool conditions won't last beyond Tuesday due to a ridge of high pressure building eastward with time.
Northwest flow sets up aloft, which is the same flow we experienced during the heat wave. If you recall, we saw brief relief from the heat due to disturbances riding up and over the ridge and across the Ozarks. We could see that same situation set up at times this week. The days in which I'm seeing a disturbance tracking close or across the Ozarks is on Wednesday and Saturday. There is not a big signal for rain this week and is only subtle at this point. Timing and location is still a big question mark. The ridge is forecast to also build eastward with time and cause temperatures to heat up once again. We'll be back in the 90s on Wednesday and staying that way through the weekend.
