The yellow light is up on our Severe Weather Tracker ...

We are tracking an upper level low that will bring widespread rainfall to the region today. Moderate to heavy rain possible for areas along and north of I-90.  Most of the area will have a good chance of a quarter to a half inch of rain, with more than a half inch from Missoula north to Kalispell.  Pockets of up to three quarters of an inch to an inch will be possible from the Superior area northeast through the Mission Valley to Glacier Park.   Debris flows and some flooding are possible in the park, so tourists should be aware of these cautions. Lighter amounts are expected around Bozeman and Butte, although these areas will also see beneficial rainfall. Rainfall totals for Butte and Bozeman should stay under a quarter of an inch.

Cooler temperatures will occur with highs only in the 60s to near 70s and low in the 40s and lower 50s.

A brief break may occur Thursday night before more showers develop on Friday.  As the storm moves out of the area, the showers will end during the day on Saturday.  Continued cool this weekend with highs in the 60s to around 70s.

A BIG warming trend is then expected next week.  Sunshine will return and highs will warm to the 70s Monday, the 70s and lower 80s Tuesday and the 80s to lower 90s by Wednesday, making it the warmest weather thus far in 2014.
