KEY MESSAGES

- Showers and even a few thunderstorms can be expected to skirt the area early Wednesday.

- Thursday will be the warmest day this week with above to much above normal temperatures.

- A cold front will bring wind and cooler temperatures this weekend.

DISCUSSION

SYNOPTIC SETUP:

Large upper trough currently over the Gulf of Alaska will keep the area under a generally SW flow with some shortwave ridges through most of the week. That will mean temperatures will be above normal with a couple disturbances bringing the chances of showers/storms.

The first disturbance moves in Wednesday that looks to mainly affect the SE zones as it moves NE into ND.

Thursday looks to be the warmest day this week with highs in the 80s area-wide, a good 10-20 degrees above normal!

The trough will help to spin up a strong surface low over Alberta by Saturday. A brief shower is possible with or ahead of a cold front moving through but is looks like wind and cooler air moving in will be the main weather elements as a strong dry slot moves in Saturday. A Lake Wind Advisory will probably be needed for Friday and Saturday.

Look for temperatures to be cooler Sunday and Monday with the chance of showers as an upper disturbance moves in.

FORECAST CONFIDENCE & DEVIATIONS: Confidence with temperatures and the potential for windy conditions Saturday seem to be increasing as the strong incoming system should help force these conditions. Confidence in the intensity of the showers over the weekend remains low.

Otherwise, generally followed what NBM gave for numbers. TFJ
