DISCUSSION

Today and Tomorrow: Northwest flow remains established across the forecast area today. An influx of moisture has resulted in expansive stratus and light snow for the northern and central mountains. Minor impacts area possible mainly at the pass level. This moisture will stick around until mid day tomorrow, so the snow continues overnight and with showers decreasing in the morning. Also, winds are still gusty in the mountains therefore some blowing snow is possible at times.

Wednesday Onward: An anamolous ridge will build over the western US causing conditions to warm up and dry out. In fact, temperatures end up 20 to 30 degrees above normal by late week. This will result in record highs into the weekend. More specifically temperatures will range from near 90 degrees in the Utah canyon country to near 70 degrees in the mountain towns.

The low stratus ceilings are beginning to lift. However, some northern and central mountain areas will have persistent low and mid level clouds through most of the forecast period, which could lead to ceilings below ILS breakpoints at times. Gusty winds up to 15 to 25 kts are possible this afternoon, particularly art KASE, KEGE, KTEX, KDRO, and KHDN. VFR conditions are generally expected to prevail, but there is a low chance of impacts from precipitation at KHDN late tonight.
