DISCUSSION

WEATHER PATTERN OVERVIEW:

The intense low pressure centered over the Canadian Prairies is slowly weakening. Expect the winds and the snow showers across the region ot slowly diminish through Sunday.

The next system will move northeast from the central Rocky Mountains late Sunday into Monday. This will bring another round of rain and snow, mainly to the southeast zones. Models are still trying to figure things out, decreasing the qpf across the central zones and holding nearly steady for the SE zones. Current snow totals are close to an inch from NW Prairie county west along the southern border of Garfield and Petroleum counties. 12z HREF keeps most of the snow along and south of Interstate 94.

Tuesday into late next week, expect a very gradual uptick in temperatures, returning to near normal by Thursday or Friday. With the upper trough overhead, there may be a stray rainshower affecting a part of the CWA through Thursday.

A ridge looks to move in Friday and should provide the area with above normal temps and dry conditions.

FORECAST CONFIDENCE & DEVIATIONS: No deviations from NBM were made. TFJ
