Sunny days ahead until at least Thursday

(TULSA, Okla.) For the first half of the work week, a closed low is predicted to make it near the Ohio River valley by Tuesday morning, while another longwave trough moves onshore over the Western continental United States. Between these two features, a ridge of high pressure is expected to set up across the Plains with upper level northwesterly flow over the County Warning Area. This will allow for near seasonal average high temperatures and cool overnight temperatures through Wednesday. Also, during this time, a surface boundary is forecast to position itself near the Red River, which could allow for isolated precipitation Tuesday and Wednesday. However, with uncertainty on where exactly this boundary sets up and available moisture from the north to easterly surface winds north of the boundary, we will hold off on adding precipitation to far Southeast Oklahoma for now. During the second half of the week, the low-pressure system (having dropped southeast into the Southeast U.S.) is forecast to finally begin lifting northeast. This will allow for the ridge over the Plains to break down and the wave over the Western CONUS to begin trekking eastward into the Plains. The result for the CWA will be a warming trend into the weekend as southerly flow transporting low level moisture returns to the region. Within the more zonal/west southwesterly upper flow, shower and thunderstorm chances becoming possible Thursday into the weekend for the area. Monday Sunny, with a high near 78.
