A WINTER WEATHER ADVISORY is in effect for elevations of 6,000′ and above in southwest and south-central Montana tonight into Tuesday.

Sunday’s powerful blizzard has left snow and record cold in place, with more snow in the forecast.  An area of low pressure will move up through southern Montana Monday night into Tuesday morning.  Snow will be heavier along and south of I-90, but some snow will reach as far north as Helena, Great Falls and Lewistown.  This storm will not be as strong as the blizzard, but more spring snow will accumulate in the state.  The mountains of southwest and southcentral Montana could see as much as 10″, with the lower elevations accumulating a coating up to a few inches.  Travel over mountain passes and in southern Montana will be slippery with snow accumulating on road surfaces.  There will be more sun and slightly warmer temperatures farther north.  Highs will be in the 30s and 40s.  May 1st is Wednesday, and it will start out cold with early morning temperatures in the 10s and 20s.  By afternoon, a warmer west wind will develop and push temperatures up into the 50s.  A few isolated showers and mountain snow showers will pop in the afternoon.  Thursday, another disturbance will move through the state with scattered showers and thunderstorms in the lower elevations, and a few snow showers in the mountains.  Friday will be windy and warmer with temperatures in the 50s to around 60.  This weekend, another strong front will drop south from Canada on Saturday.  Snow and wind are likely to increase across much of the state again, with some snow lingering into Sunday morning.  After the weekend, temperatures will once again slowly modify back to near normal temperatures for the beginning of May.

Have a great day.
