SPC Jan 8, 2025 1930 UTC Day 3 Severe Thunderstorm Outlook
SPC 1930Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 1233 PM CST Wed Jan 08 2025 Valid 101200Z - 111200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast through Friday night. ...Central to eastern Gulf Coast... Thunder potential appears quite limited on Friday as poor to weak mid-level lapse rates persist downstream of a positive-tilt longwave trough. Buoyancy inland appears negligible, but meager MUCAPE over the north-central Gulf may be sufficient for a thin, low-topped convective line to shift east through the day from coastal southeast LA through the FL Panhandle.

Severe thunderstorms are not forecast through Thursday night. ...TX/LA... A northern-stream shortwave impulse should phase with an initially closed mid/upper low in the Gulf of CA vicinity, yielding a longwave trough from south-central Canada to northwest Mexico by Thursday night. Downstream low-level warm-moist advection will foster increasingly widespread precipitation across the South-Central States on Thursday as a surface cyclone becomes established off the western Gulf Coast. Despite ample

Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0337 AM CST Wed Jan 08 2025 Valid 111200Z - 161200Z ...DISCUSSION... A series of mid-level troughs will move across the continental U.S. through the middle of next week, as a prevailing northwest flow pattern continues. In response, a cold and dry airmass will remain anchored over most of the continental U.S. throughout the Day 4 to 8 period, making thunderstorm development unlikely in most areas. Read more

Very isolated thunderstorms will be possible Wednesday night across parts of west Texas. ...West Texas... A closed mid/upper low will migrate slowly across northwest Mexico on Wednesday. Deep-layer southwesterly flow ahead of this feature will result in a warm advection regime atop a sub-freezing boundary-layer across portions of Texas Wednesday night into early Thursday. Meager elevated instability may develop within the 750-500 mb layer amid increasing moisture, cold
Hydrologic Outlook issued January 7 at 2:41PM AKST by NWS Anchorage AK
ESFAFC Recent and continuing warm weather and widespread rainfall have led to rising creek and stream levels from the Kenai Peninsula north into the Mat-Su Valleys. Overflow has been reported on creeks and over existing trails. Increased streamflows may also lead to localized ice jams. Those traveling on backcountry trails are encouraged to take extra caution around area streams, rivers and trails, as water may degrade ice and create difficult or hazardous conditions. For Urban areas, recent snowmelt and rain is ponding on area roads, and will likely linger until drains are cleared or melt. Motorists should exercise caution driving

Downstream of this wave, warm-moist advection at 700 mb should eventually yield scant buoyancy with mixed-phase states in elevated parcels amid steep mid-level lapse rates. Isolated convection should develop overnight Wednesday into early Thursday, most of which should occur atop
