Day 2 Convective Outlook  
NWS Storm Prediction Center Norman OK
1106 AM CST Sun Dec 29 2024

Valid 301200Z - 311200Z

...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorm chances appear low on Monday.

...Synopsis...

An upper shortwave trough will lift northeast across New England
toward the Canadian Maritimes on Monday. At the surface, deep low
pressure over southern Ontario will lift north while an attendant
cold front pushes offshore the Atlantic coast. In the wake of the
Northeast U.S. system, another upper shortwave trough will migrate
from the northern/central Plains to the Mid-MS/Lower OH Valley
region. A surface low is forecast to move from the KS/NE to IL/IN. A
prior cold frontal passage into the Gulf of Mexico will result in
richer boundary-layer moisture remaining confined to the immediate
coastal area despite increasing southerly low-level flow across the
south-central U.S. Meager elevated instability, generally less than
200 J/kg MUCAPE, will overspread portions of the Lower MO/Mid-MS
Valley ahead of the surface low and upper trough. While a couple of
lightning flashes are possible with developing precipitation during
the evening/overnight, coverage is expected to remain less than 10
percent, precluding a general thunder delineation.
