KEY MESSAGES
- Showers moving east across southern Saskatchewan may briefly drop south across the International border briefly today.
- Gradual warmup is expected through Friday.
- Chances of widespread showers return Thursday night and exiting over the weekend. 0.50" to 1.00" amounts are possible.
DISCUSSION
SYNOPTIC SETUP:
An upper trough deepening along the Pacific NW coast is closing off over northern California while a northern stream trough is moving east across the Prairie Provinces. This trough is responsible for clouds and scattered showers from north-central Montana into southern Sask. These showers are expected to stay in north of the International border today but a few sprinkles cannot be ruled out from Whitewater to Plentywood today. Elsewhere, clouds will lift northeast allowing increasing sunshine and temperatures starting to recover a bit.
The closed low is expected to lift into Montana by this weekend with amounts from 0.50" to 1.25" in mainly the eastern and central zones with lighter amounts in the west. Most of the rainfall is expected to move in Friday night and last into Saturday morning. thunderstorms Friday night will produce locally heavy rainfall.
A weak upper ridge is expected in the wake of the departing upper low by Monday for drying conditions and another slight bump in temperatures.
FORECAST CONFIDENCE & DEVIATIONS: - NBM pops were too dry initially for early this morning, so blended with higher pops through today (Wednesday). Other NBM elements looked good.
- Confidence in rain chances this weekend are moderate. There is a higher confidence in rainfall chances across the eastern zones of the CWA. Less confidence moving further into western zones.
- Confidence in amounts are increasing but remain inconsistent over the central zones.
