SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0130 AM CST Sat Jan 30 2021 Valid 011200Z - 021200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected on Monday. ...Synopsis... Guidance is in good agreement that the upper pattern will feature a western CONUS ridge and an eastern CONUS trough early Monday morning. These features are expected to move gradually eastward throughout the day, with the upper trough ending the period extending southward along the East Coast and the upper ridge covering much of the central CONUS. An additional shortwave trough will likely extend from British Columbia southwestward into the northwest Pacific Ocean early Tuesday morning. Dry and stable conditions are anticipated across the CONUS, with the lack of buoyancy precluding thunderstorm development. A few deeper convective cores are possible within the frontal band associated with the surface low attendant to the British Columbia shortwave as it moves ashore. However, lightning coverage should remain less than 10%. ..Mosier.. 01/30/2021
