MD 2249 CONCERNING SNOW SQUALL FOR EASTERN AND FAR NORTHEAST OHIO...WESTERN AND NORTH-CENTRAL PENNSYLVANIA...SOUTHERN NEW YORK
Mesoscale Discussion 2249 NWS Storm Prediction Center Norman OK 1247 AM CST Thu Dec 05 2024 Areas affected...Eastern and Far Northeast Ohio...Western and North-central Pennsylvania...Southern New York Concerning...Snow Squall Valid 050647Z - 051045Z SUMMARY...Snow squall conditions are expected over next several hours from eastern and far northeast Ohio into western and north-central Pennsylvania and southern New York. Heavy snow and strong wind gusts will be associated with these bands. DISCUSSION...A line of shallow convection, associated with snow and strong gusty winds, is located across eastern and far northeast Ohio. Hi-resolution 88D radar suggests that heavy snow is ongoing within the more intense parts of the band. In addition, the latest surface observations near the band are measuring wind gusts near in the 45 to 55 mph range. On radar, the band is moving quickly to the east-northeast at 50 to 60 knots, meaning that it will impact much of far eastern Ohio and western Pennsylvania over the next few hours. The snow squall is expected to remain intact as it moves into parts of north-central Pennsylvania and southern New York later this morning. Impacts from the band will be the onset of heavy snow, visibilities quickly dropping to less than 1/4 mile, and wind gusts increasing to near 55 mph. ..Broyles/Guyer.. 12/05/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0223 AM CST Thu Dec 05 2024 Valid 071200Z - 081200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Scattered thunderstorms are likely across a large portion of Texas on Saturday. No severe thunderstorms are expected. ...Synopsis... The southwest CONUS trough which has been present much of this week will start to move east on Saturday with strengthening mid-level flow through the day with a strengthening low-level jet during the evening and into early Sunday. The surface front will remain along the coast and thus, any surface based instability is forecast to remain offshore. Some elevated instability will be present across much of Texas which will result in scattered thunderstorm development as the low-level jet strengthens. However, elevated instability will be quite weak and therefore, no severe thunderstorms are anticipated. ..Bentley.. 12/05/2024 Read more

Isolated to scattered thunderstorms are possible from southeast New Mexico to central Texas. No severe thunderstorms are expected. ...Synopsis... On Friday, a mid-level trough will slowly drift eastward along the Arizona/Mexico border. Stronger mid-level flow will round the base of this trough Friday afternoon and emerge into the southern Plains Friday night and early Saturday. Some moisture return will occur above the surface front which will result in weak instability across Texas and perhaps into southeast New Mexico. As stronger mid-level flow emerges across the southern Plains, isolated to scattered elevated thunderstorms are possible from southeast New Mexico and Far West Texas, to parts of central Texas. However, weak instability should keep any severe weather threat limited. ..Bentley.. 12/05/2024 Read more

Fire weather concerns will be low on Friday, as much of the CONUS remains under a cool air mass with widespread precipitation across the eastern US.

Some locally Elevated fire weather conditions will be possible. Areas are expected to remain localized, which will preclude the need to add areas at this time. ..Thornton.. 12/05/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more
