DISCUSSION

KEY MESSAGES: - Scattered mix of rain and snow is expected through most of the week. Snow accumulations look generally light. - A dry and warm weather pattern will develop by later this weekend.

WEATHER PATTERN OVERVIEW:

A broad upper trough will linger over the western states through much of the week. A strong embedded disturbance currently over the dakotas will lift off to the northwest this evening, allowing for some partial clearing and a brief period of generally quiet weather tonight.

The next low pressure wave is expected from the northwest early Thursday. This will bring another round of precipitation for Thursday into Friday. With colder air moving in from the north behind this system, any mixed precipitation will change over to snow on Thursday evening. Snow accumulations will be generally less than two inches, and could be even less due to the somewhat warmer ground and the potential for rain at times.

For the weekend, the flow pattern changes to bring in a warmer high pressure ridge from the west. This should provide much drier and warmer conditions into next week.

FORECAST CONFIDENCE & DEVIATIONS:

Confidence is moderate with Thursday's disturbance as historically the forecast models can struggle with storms with a northerly trajectory. Confidence is high in the ridge rebounding and temperatures warming starting this weekend.

AVIATION

VFR to MVFR conditions.

A broad upper trough will remain overhead through the TAF period. Weak ridging on the back side of an exiting storm system over the Dakotas will bring a short lived improvement in conditions this afternoon through early Thursday. Around sunup on Thursday morning another frontal feature will drop southward out of Canada bringing periodic MVFR conditions and light snow.
