A compact mid-level low will translate east across the Southwest on Sunday which will result in lee cyclogenesis in the southern/central High Plains. As surface high pressure across the Midwest translates east, favorable low-level trajectories and strengthening flow across the Gulf and southern Plains will initiate significant moisture return across Texas. The initial mid-level low will weaken as it moves across the Plains and into the
Hydrologic Outlook issued February 26 at 12:40PM MST by NWS Riverton WY
ESFRIW Low elevation snowpack of around 2 to 8 inches exists across much of the northern portion of the Bighorn Basin including mountain foothills. This snowpack contains an estimated 1 to 3 inches of Snow Water Equivalent (SWE). Warmer temperatures occur Thursday through Sunday with highs nearing or exceeding 50 degrees (Feb 27 - Mar 2). The upcoming warm temperatures, combined with the low elevation snowpack, could result in melting and injection into local rivers and streams. Ice break up on the Bighorn and Nowood Rivers is possible as well, and could lead to ice jamming and potential resultant flooding.

ESFLKN Upper level high pressure will bring warming temperatures to northern Nevada. This will allow for snowmelt from the mountains to increase, with runoff occurring into area rivers and creeks. Two waterways that are of concern at this time are Martin Creek in Humboldt County and the Owyhee River near Mountain City. With snowpack remaining and subsequent frozen ground, snowmelt will runoff into these two waterways. This will cause higher than normal flows over the next two days. Residents and outdoor enthusiasts are urged to use caution when walking along the riverbank as the water will be flowing rapidly with

ESFGGW Where: All of Northeast Montana. When: Through the end of February. What: A ridge will bring temperatures to above average through the end of this weekend. Although, temperatures each night will drop near or below freezing. Warm daytime temperatures will increase snowmelt and lead to ponding in low lying areas. New Precipitation is not expected until Monday to Monday night when temperatures will drop back to near normal. Make sure to monitor the latest weather forecast, as well as local streams and rivers at weather.gov/ggw and water.noaa.gov/wfo/ggw.

Isolated thunderstorms remain possible across the Midwest and Ohio Valley this evening. Severe thunderstorm threat is low. ...01z Update... Low-amplitude short-wave trough is ejecting across the Ohio Valley. Large-scale forcing ahead of this feature is primarily responsible for scattered convection that currently extends from western PA, arcing southwest along the Ohio River into southeast MO. While much of this activity is not producing lightning, isolated thunderstorms are noted

Severe weather potential will be low to start the period with northerly flow across the Gulf on D4/Saturday. On D5/Sunday, a compact mid-level low will translate east across the Southwest which will result in lee cyclogenesis in the southern/central High Plains. As surface high pressure across the Midwest translates east, favorable low-level trajectories and strengthening flow across the Gulf and southern Plains will initiate significant moisture return across Texas.

ESFGGW Where: All of Northeast Montana. When: Through the end of February. What: As arctic air pushes east into the central plains, a ridge will move in to bring temperatures above average through the end of next week. Although temperatures each night will drop near or below freezing, warm daytime temperatures will increase snowmelt and lead to ponding in low lying areas. There is moderate confidence precipitation amounts are expected to remain below one tenth of an inch Sunday night into Monday night, so little to no impact on runoff is expected from this event.
