Isolated thunderstorms will be possible on Monday across south Texas. Severe storms are not expected. ...Synopsis... An expansive mid/upper-level trough over the eastern CONUS will move slowly eastward on Monday, while upstream midlevel height rises reinforce surface high pressure from the northern Plains into the Southeast. As a result, boundary-layer moisture will remain confined to the Gulf of Mexico, limiting thunderstorm potential across much of the CONUS. The

Thunderstorms are not expected on Sunday. ...Synopsis... A large upper-level low centered over Ontario/Quebec provinces will persist through Sunday, with an expansive area of cyclonic flow across much of the central and eastern CONUS and a ridge over the western states. Surface high pressure from the Plains states into southeast U.S. will reinforce generally dry/stable conditions. With the exception of portions of deep South Texas, appreciable low-level moisture/instability will

Thunderstorms are not forecast for today. ...Synopsis... Much of the CONUS will remain under the western periphery of a broad mid-level trough, which will reinforce surface high pressure and associated cool surface conditions. Static stability over the CONUS will limit organized thunderstorm potential. A couple of lightning flashes cannot be ruled out over portions of Lakes Erie, Ontario, and immediate adjacent shorelines within lake effect snow bands. However, the
