A low-amplitude upper-level ridge will be centered over the central CONUS on Monday and is forecast to slowly amplify through the week. As this occurs, northwest flow will strengthen from the northern Plains to the western Great Lakes and Midwest with high quality moisture in place. Severe weather may be possible during this period (most likely D5/Tue to D7/Thu). Most guidance shows convective precipitation signals and likely MCSs each afternoon, but based on the timing and amplitude of shortwave trough passages within the northwesterly flow, the uncertainty in location remains too high at this time to introduce probabilities. Farther east, an unusual progression of the upper-air pattern appears increasingly likely with a developing upper low over the Gulf Stream retrograding into New England on Monday and Tuesday. This general progression has been supported by the last several runs of the GFS and ECMWF and an even farther west shift occurred with the 00z ECMWF and EC ensemble which would bring an even larger warm sector onshore. This will need to monitored for the potential for at least some severe weather activity. Read more View the full article Quote Link to comment Share on other sites More sharing options...
