Day 2 Convective Outlook  
NWS Storm Prediction Center Norman OK
1131 AM CDT Mon Oct 05 2020

Valid 061200Z - 071200Z


The risk for severe thunderstorms will remain negligible Tuesday
through Tuesday night.


An amplified upper pattern with a trough in the east and a ridge in
the west will persist across the CONUS on Tuesday. Warm and dry
conditions are expected beneath the western ridge. Further east,
deeper boundary layer moisture will remain confined to the Gulf
Coast and into the southeastern Atlantic coastal vicinity. Isolated
thunderstorms will be possible across Florida northeastward along
the GA and SC/NC coast/near-shore waters vicinity where stronger
heating will allow for weak destabilization. Low level confluence
and sea breeze interactions will be the main drivers of any
thunderstorm activity in these areas. 

Further north across the upper Great Lakes area, strong
northwesterly flow will overspread the region as the upper trough
pivots east/northeast through the period. Steep midlevel lapse rates
and cold temperatures aloft will aid in development of shallow
convection, and a few thunderstorms are possible, mainly during the
afternoon into the early overnight period.
