-- Quiet and mild through Saturday -- We continue to expect a quiet and mild period from this morning, right on through most of Saturday. The upper trough that plagued the area with clouds and showers the last couple of days has moved well east of the area. A short wave ridge will bring a good deal of sunshine today, with just some cumulus clouds developing this afternoon. We do see a short wave trough push through the region on Thursday. This system should have little to no impacts on the area. The synoptic scale pattern favors more broad scale subsidence that will dominate over the weak impulse passing through. In addition, the atmosphere is quite dry, so generating rain will be quite difficult. Once the short wave moves through Thursday, ridging at the surface and aloft will assure more sunny days and mostly clear nights. Temperatures will gradually warm through Saturday, as the cold pool aloft shifts east, and warmer temps advect over the area. -- Warmer with periodic chances for storms Sat night and beyond -- Rain chances will increase markedly beginning Saturday night, and will remain possible through the end of the period on Tuesday. It will not be raining all of the time by any means, but the chance will exist for some rain for each period beyond Saturday. The more unsettled weather pattern will result from return flow setting up behind the departing high, and ahead of a sfc low in the Plains. A warm front will approach the area, and looks like it will stall out as it encounters a more zonal upper flow becoming established over the northern tier of the country. A surge of warm and moist air will become established over the area, and stick around. Short waves embedded in the zonal flow, interacting with the warm and humid air mass expected to be in place, will help to generate clusters of storms that should ride along the stalled out boundary. The timing and exact placement of any storms is quite uncertain this far out. We will fine tune the forecast as we approach that time frame.
