A significant upper-air pattern change is expected this week. This SOI crashed which is a good signal troughing will develop over the central CONUS. This is expected to occur this week as a low pressure system ejects out of the Rockies on Tuesday. This will allow a cold front to move southward into North Texas as a lobe of energy breaks off from the low pressure system. These features will combine to bring numerous showers and thunderstorms to North Texas by Wednesday. Temperatures will be able to drop into the 80s for highs and drop into the 60s for overnight lows. What a nice break from the heat of the last few weeks! The front will wash out well south of the forecast area, and winds will be able to return back to the south/southeast by next weekend. This will ensure temperatures warm back up to normal values (which are coming down).
