Area Forecast Discussion National Weather Service Pueblo CO 1135 PM MDT Sat Apr 7 2018 .SHORT TERM...(This evening through Sunday) Issued at 243 PM MDT Sat Apr 7 2018 A disturbance will move across the state tonight, bringing precip chances to much of the area. This system is not all that cold, and overnight lows at many of the lower elevation locations are expected to be in the 30s and snow that falls may have a hard time accumulating. However, temps over the far eastern portions of the plains later tonight, are expected to be colder than much of the rest of the plains, and snow may be more likely to stick in those locations, although accumulations are forecast to be light. There may also be some freezing drizzle tonight over some of the far eastern border areas. The Continental Divide will be hardest hit with snow tonight, with the Mosquito and Sawatch mtns seeing the highest snow amounts. Other mtn areas should see lighter accumulations than the central mtns. The weather disturbance will exit the state in the early afternoon and precip will mostly come to an end. However, there could be some lingering light showers in areas thru the afternoon. It is expected to be breezy or windy Sun afternoon, with the San Luis Valley probably seeing winds of 25 to 35 mph and some higher gusts. At the same time, humidity values in the San Luis Valley are expected to fall to between 10 and 15 percent. This combination of windy conditions and low humidities, along with the dry fuels, has prompted the issuance of a Red Flag Warning for the San Luis Valley from 1 PM through 7 PM Sunday. .LONG TERM...(Sunday night through Saturday) Issued at 243 PM MDT Sat Apr 7 2018 There is still good agreement between the GFS and ECMWF through the extended period leading to higher forecast confidence. Ensemble spreads are also relatively small through the extended period as well. Sunday night through Monday...embedded energy in the northwest flow aloft will continue to move across Colorado through Monday afternoon. This will bring light snow to the Central Mountains through the period with minor accumulations possible. Periods of light rainfall will also be possible from the Palmer Divide, southeast across the Eastern Plains Sunday night through Monday afternoon. QPF amounts will be light, and coverage does not look overly great at this time fort he Plains. Temperatures will warm on Monday afternoon into the 60s for highs. Tuesday through Wednesday...high pressure over Utah will transition east across Colorado and into the Central Plains ahead of an approaching storm system for Thursday. Expect dry weather both days with warming temperatures. Highs will warm through the 70s into the 80s for the Plains. Humidity values will fall on Wednesday below 15 percent, however, winds will be marginal for fire weather concerns at this time on Wednesday. This will need to be monitored. Thursday through Saturday...a strong upper level storm system is forecast to move across the area late in the work week. Ahead of the storm system, southwest flow will increase across Colorado leading to dangerous fire weather conditions. Widespread southwest winds gusting to near 45 to 50 mph may be possible, and humidity values will fall well below 15 percent, while highs reach into the 70s and 80s Thursday afternoon. Plan now to postpone any outdoor burning. Snow is forecast to move into the Continental Divide Thursday afternoon and persist through the day on Friday. Expect a cold front to push across Colorado by Friday morning with strong westerly winds behind it. Even with cooler temperatures in the 50s and 60s, near critical fire weather conditions will likely exist across the region and will need to be monitored closely. In addition, snow along the Continental Divide should continue through the day before dissipating by Friday evening. By Saturday, northwest flow will take over and light snow will likely linger over the Central Mountains through the day with minor snow accumulations possible. Conditions over the Plains will still be breezy, but less than Thursday and Friday.

This will result in heavy snow over the central mountains above 10,000 feet where 4 to 8 and locally up to 10 inches of snow is expected by noon on Sunday. For the rest of the mountain areas, local accumulations of 1 to 4 inches will be possible above 10,000 feet. This next system looks too warm for snow at the lower elevations so mainly rain showers are expected tonight. However, if any cold air remains trapped near the surface, some pockets of light freezing rain may develop over the far eastern plains. This would primarily impact Kiowa, Bent and Prowers Counties. .DAYS TWO THROUGH SEVEN...Sunday through Friday A couple of upper disturbances tracking east across the region will keep a somewhat active pattern in place. The first will affect the forecast area during the day Sunday, bringing one to three inches of new snow to the higher terrain as well as some rain to the lower elevations before tapering off. The next disturbance will arrive soon after, bringing another quick one to three inches of new snow for the mountains Sunday night through Monday morning. Dry conditions and warming temperatures are forecast for Tuesday through Thursday, with fire danger likely nearing critical levels for Thursday. Another low pressure system will track across the state Thursday night and Friday, bringing accumulating snow to the higher terrain. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be likely in the mountains tonight. 27/10
