Synopsis...
In Mid-Upper Levels...Cyclonic Flow Will Cover Most Of Conus From
Great Basin And Nrn Rockies Ewd. Strongest Embedded Shortwave
Trough -- Now Evident In Moisture Channel Imagery Over Mb -- Will
Move Across Upper Great Lakes Region And Adjoining Portions Ont This Period...Well-Removed From Enough Low-Level Moisture For Tstms.
At Sfc...Cyclone Now Over Nwrn Mn Should Continue Deepening While Moving Esewd Across Lh...Ahead Of Mid-Upper Perturbation. Attached Cold Front Will Cross Great Lakes...Mid-Upper Ms Valley And
Nrn/Central Plains This Period. However...Prior Fropas And Related/ Successive Continental Anticyclones Will Keep Theta E Too Meager To Support Tstms Over Conus.
Coastal Se Fl...
Weak Sfc Low Near Se Fl Coast Is Expected To Move Slowly Newd Today. Attendant Weak Low-Level Convergence May Enhance Potential For Continued Showers. Over Gulf Stream...Sufficient Marine Heat/Moisture Fluxes May Exist To Support Deeper Convection. However...Poor Mid-Level Lapse Rates And Related Stable Layers Aloft In Fcst Soundings Indicate Tstm Potential Is Too Weak/Conditional For Gen Thunder Outlook.
