A strong mid-level trough will amplify across the East Coast on Thursday with a strong cold front sharpening along the Appalachians and moving into the Atlantic. Given the persistent continental airmass preceding the cold front with minimal moisture recovery, instablity should be quite weak. However, forecast soundings show some weak instability which could promote a few lightning flashes across the Carolinas and vicinity. In the wake of the cold front, dry air will remain across

ESFRIW Low elevation snowpack of around 4 to 10 inches exists across much of the northern portion of the Bighorn Basin including Greybull, Lovell, Powell, and Cody. This snowpack contains an estimated 1 to 3 inches of Snow Water Equivalent (SWE). Temperatures beginning are expected to climb into the low 40s to near 50 degrees each afternoon through next weekend. Warmest temperatures look to occur Friday through Sunday (Feb 28 - Mar 2). The warm temperatures, combined with the significant low elevation snowpack, could result in significant melting and injection into local rivers and streams. Ice break up on the
Hydrologic Outlook issued February 23 at 1:56PM MST by NWS Pocatello ID
ESFPIH Temperatures will continue to warm into early next week, increasing low elevation snowmelt and runoff, potentially leading to minor lowland flooding. Locations most prone to rapid snowmelt include areas below 6000 ft across the Eastern Magic Valley, Lower Snake Plain, and South Hills, where snow pack still exists. In these areas, the increased runoff on top of frozen or saturated ground may lead to ponding of water or sheet flooding in low lying or poor drainage areas, along with rises on small streams and creeks. These warming temperatures will peak on Monday, with afternoon highs reaching the 50s across

ESFMSO Where: Powell, Deer Lodge, and Silver Bow Counties in Montana and Lemhi County in Idaho. What: A significant warm up will continue through Monday, February 24. High temperatures will reach into the 40s, with overnight temperatures near or above freezing. Rapid lowland snowmelt will lead to ponding of water in low lying areas, especially in areas of poor drainage and/or in basements/crawlspaces. Ice jam releases are also a concern on small streams and/or creeks, and may lead to localized flooding. Rain showers will bring precipitation totals up to 0.20 inches across valley areas Sunday into Monday, with upwards of

ESFSEW An atmospheric river this weekend, followed by another frontal system later Monday will result in heavy rain at times over the area. Total precipitation amounts in the mountains will range from 3 to 5 inches, with locally heavier amounts possible in the mountain. Snow levels will rise above 7000 feet, will result in snow melt at low to mid elevations. The most likely areas for river flooding will be for rivers flowing off of the Cascades and Olympics. Urban and small stream nuisance flooding and rainfall-induced shallow landslides will also be possible. Please monitor the latest river forecasts from
