Area Forecast Discussion National Weather Service Salt Lake City UT 958 AM MDT Thu Jun 13 2019 .SYNOPSIS... A weak upper level disturbance will cross the Great Basin today into Friday. A weak ridge is expected for Saturday followed by another disturbance on Sunday. && .DISCUSSION...An area of 300mb wind divergence in combination with an increase of moisture at mid levels has produce instability over northwest Utah this morning. This area should expand eastward this afternoon as the trough over northern Nevada moves east. Have increased PoPs across the north this morning but decreased them over the Uinta Basin as dynamics remain far removed from there. The dry low levels will combine with the added dynamics of the trough moving into western Utah this afternoon and early evening to give a threat of severe thunderstorms over mainly the west deserts from about Juab county northward late this afternoon and from the southern to northern Wasatch Front early this evening. Strong erratic winds will be the main threat. The HREF ensemble shows an organized area of high radar reflectivity forecast from near Wendover northward at 22Z moving east to the Wasatch Front by 01Z and the western Uintas and southwest Wyoming by 03-04Z. Updated the forecast over southern Utah for more sun this morning but as the trough from Nevada moves into Utah later today the cloud cover will increase as well as the threat of showers and thunderstorms. && .AVIATION...An area of high-based showers will remain north of the terminal area through the balance of the morning. Similar high-based showers will develop again during the afternoon, with a chance of thunderstorms in vicinity of the terminal in the 23Z to 04Z window. Prevailing winds will remain light from the southeast through around 18Z, then switch to the northwest. A 40 percent chance of gusty and erratic winds at the terminal will exist with some of the high-based showers and storms beginning around late afternoon and continuing through mid-evening. && .FIRE WEATHER...A weak trough will cross the region today through Friday. Southwest winds will increase today ahead of the trough, especially over southern and western portions. Scattered showers and thunderstorms have developed over the northwest portion of Utah (zone 478) and will continue to develop this afternoon, mainly over the higher terrain, then move off across the lower elevations through this evening. Any showers and thunderstorms will be particularly capable of producing erratic strong gusty winds today, especially across the west dessert where gusts may be severe. Winds will shift to the northwest in the northern zones later today and across the remainder of the region by Friday. A weak ridge will be over the area Saturday but enough moisture may linger for isolate thunderstorms over mainly the high terrain. Afternoon min RH values will be a bit higher Friday and Saturday. && .SLC WATCHES/WARNINGS/ADVISORIES... UT...Flood Watch through Friday morning for UTZ003. WY...None. && PUBLIC...Struthwolf AVIATION...Conger FIRE WEATHER...Struthwolf For more information from NOAA's National Weather Service visit... http://weather.gov/saltlakecity For frequently asked questions about the Area Forecast Discussion visit... http://weather.gov/saltlakecity/general/afd_faqs.php
