Latest on the wintry mess Sunday for Southern Idaho

TWIN FALLS, Idaho (KMVT/KSVT) Moisture from the next stronger Pacific system has moved into Southern Idaho Sunday morning and locations as of 9 a.m. were experiencing snow, sleet freezing rain and a few locations were seeing rain. Temperatures were also slowly trying to warm. At the Magic Valley Regional Airport temperature at 9 a.m. was 31 degrees, it was above freezing with 34 in Burley, in Jerome it was still in the 20s at 28 degrees. Many local sensors in Twin Falls were also reporting temperatures still in the 20s as of 9 a.m. Timing the warming will be the biggest challenge for Sunday and the going weather forecast.

Here is what you can expect Sunday into Monday across Southern Idaho

Sunday morning until midday – Snow mixed with sleet and even freezing rain is likely during this time. So far Sunday morning not much precipitation had fallen across Southern Idaho. This will keep snow and freezing rail amounts low. Temperatures are what we watching during this period as this is where the challenge in the forecast remains. When do we break above freezing for most of Southern Idaho? We still anticipate most temperatures rising above 32 degrees Sunday afternoon and into Sunday evening.

Sunday noon to 6 pm Sunday – It comes down to temperatures but we anticipate the changeover to all rain during this time. Some valley locations will continue to see snow, wintry mix of sleet or freezing rain before going over to all rain. Boise has a high potential of seeing freezing rain longer so it may be recommended if you don't have to travel to the Treasure Valley today don't. The Magic Valley will not be as bad.

Sunday 6pm into Monday – With warmer air, most of the precipitation will fall as rain below 6000 feet. Mountains will see an additional 4 to 8 inches of snow. Liquid amounts of precipitation could range from 0.4" to 0.5" by Monday evening. This along with above freezing temperatures near 40 will lead to melting of snow and localized urban flooding on area streets. With melting snow and rain falling on top of it this will be the main concern during this time. The thing we expect is temperatures to stay near or below 40. This will slow the snow melt and should help minimize the flooding concern. There are flood advisories and watches in place for the Valleys for Sunday night into Monday.
