NWS Storm Prediction Center Norman OK
0627 AM CST Sat Dec 30 2023
Valid 301300Z - 311200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not forecast across the contiguous United States
today.
...Synopsis...
Water-vapor imagery this morning shows a mid- to upper-level trough
moving ashore along the West Coast and it is forecast to partially
bifurcate, as a mid-level low evolves over northern AZ by Sunday
morning and a trough weakens over the Pacific Northwest. A band of
showers will spread inland across the West Coast during the day
before precipitation coverage decreases with eastward extent by
evening. Cool/stable conditions farther east due in large part to
surface high pressure over the Gulf will result in conditions
hostile for thunderstorm development over the central/eastern
states.
