Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 300 AM EST Sun Nov 03 2024 Valid 12Z Sun Nov 03 2024 - 12Z Tue Nov 05 2024 ...Another day of heavy rain and severe weather expected across the central U.S. before shifting east into the Arklatex, Mid-Mississippi Valley and Midwest by Monday night... ...Mountain snow moving across the Intermountain West and Rockies today will begin to taper off on Monday as the next round of mountain snow and wind quickly overspreads the Pacific Northwest on Monday... ...Above average temperatures approaching record levels will shift east from the Plains today towards the Mississippi Valley by Monday with no rain in sight along the East Coast... The ongoing active weather system over the south-central U.S. will continue to trigger additional rounds of heavy rain and severe weather for the remainder of today, with the heaviest rainfall expected to impact central to eastern Oklahoma into portions of northwestern Arkansas and southern Missouri. More energy ejecting from the upper-level trough currently spreading mountain snow across the Intermountain West will eventually consolidate a low pressure system over the central High Plains by tonight. This low pressure system will track northeastward across the central Plains followed by another low pressure system to develop over the south-central Plains on Monday. This second system is forecast to push a cold front farther eastward Monday night, ending the heavy rain threat across Oklahoma but shifting the heavy rain and severe weather threats into the Arklatex region, Mid-Mississippi Valley and Midwest by Monday night. The upper trough will usher colder than normal temperatures through much of the western U.S. for the next couple of days with mountain snow passing through the Intermountain region today, followed by the central and southern Rockies on Monday. Meanwhile, a rather strong low pressure system from the Pacific Ocean will quickly spread the next round of coastal rain into the Pacific Northwest on Monday followed by a good dose of mountain snow farther inland along with quite a bit of wind. The mountain snow will reach into the northern Rockies Monday night into Tuesday morning as the low pressure system redevelops over the northern High Plains. The greatest chances (>80%) for over 8 inches of snowfall in a 24-hour period is forecast over the northern Cascades on Monday. Be sure to prepare for winter driving conditions if traveling throughout these elevated mountain ranges and stay tuned to the latest local weather forecast. Warmer and mostly dry conditions will be felt east of the Mississippi River through early next week, besides rain chances entering parts of the Midwest and Great Lakes. A large high pressure system centered over the Great Lakes is forecast to slide eastward and off the New England coastline by Monday, ushering in warm southerly flow on the western periphery. This will support widespread above average high temperatures into the upper 60s and 70s from the central/southern Plains to the Mid-Atlantic by Monday, with 80s along the Gulf Coast States. When compared to early November climatology, the Midwest is expected to experience temperatures well above average on Monday. The anomalous warmth will then spread across the Ohio Valley into the Great Lakes by Monday night into early Tuesday as showers and thunderstorms ahead of the cold front reach into the Midwest.
