Area forecast discussion National Weather Service Salt Lake City Utah 338 PM MDT Friday Aug 28 2015 Synopsis...high pressure will bring a warming and drying trend through tomorrow. A weak frontal boundary will cross the area Saturday night...followed by a generally dry southwesterly flow for much of next week. && Short term...scattered convection that has developed over western Nevada is expected to gradually spread east over far western Utah this evening...though coverage trends will be decreasing as this convection translates into a more suppressed environment. Latest hrrr indicates full suppression by 03/04z this evening which fits the conceptual model as updrafts have formed due to differential heating and diurnal circulations over the higher terrain. Loss of this will preclude further development during the overnight hours. The previously deep closed low off the norcal coast has become more progressive as a deeper low over britcol continues its southward translation down the coast. Said progressive short wave will lift through the pacnw over the next 36 hours displacing the ridge and associated axis east of the area tomorrow. This will allow a deep southwesterly flow to ramp up across the eastern Great Basin. Associated with this wave...700 mb forecasts continue to note a weak baroclinic zone translating east through northern Nevada tomorrow afternoon that will then spread into northern Utah during the evening hours. Ahead of and associated with this area of weak lift...middle level moisture convergence should be enough to form isolated to widely scattered high based convection across the north...and a tightening S-north mslp will aid breezy southwesterly winds focused across the western valleys. 700 mb temperature trends will continue to climb in this deeply mixed environment and expect the warmest temperatures of the period to occur tomorrow...some 5-10 degrees above climatology. Said baroclinic zone will shift over central Utah tomorrow night through Sunday further suppressing the high south and east of the area. Will have to monitor potential of moisture convergence along and southeast of this boundary for isolated to widely scattered convection Sunday...but expect a temperature drop to or a few degrees back below climatology will be more notable sensibly north and west of the boundary. Long term (after 12z monday)...the 700mb baroclinic zone in far northern Utah weakens and a dry subsident southwesterly flow reinstates itself statewide by Monday afternoon. Global models are in comfortable agreement with this pattern persisting through the extended forecast...showing a mean trough over the Pacific northwest remaining centered well to the north of the County Warning Area. By Tuesday winds ramp up and temperatures in the northern half of the County Warning Area climb above normals...while the southern half remains a few degrees below norms. A modicum of instability may promote convection over the highest terrain on Tuesday afternoon. Midlevel winds increase further and remain elevated through the week. A weak 700 mb baroclinic zone brushes northwest Utah on Wednesday followed by an even drier airmass...thus shutting off the moisture tap statewide for the remainder of the work week. GFS insinuates a series of additional weak baroclinic zones nudging into northern Utah after midweek...have thus bumped temperatures down a degree or two each day. && Aviation...north to northwest winds will continue at the slc terminal before shifting to the southeast between 02-04z. && Fire weather...isolated high based thunderstorms remain possible through this afternoon across far western portions of the district and along the mountain spines of central and southern Utah. High pressure will shift east overnight through tomorrow allowing a strengthening southwesterly flow aloft to spread across the area. A weak frontal boundary approaching from the northwest coupled with the up tick in winds aloft will create breezy southerly surface winds across the western valleys tomorrow afternoon...and coupled with drying low levels will combine to produce locally critical fire weather conditions across portions of fire weather zones 478..492 and 495. This said fuels as reported remain non-critical in those areas. As the frontal boundary crosses northern Utah tomorrow afternoon/evening isolated to widely scattered high based thunderstorms are expected to form and linger into the overnight hours. Deep southwesterly flow will remain in place through much of next week allowing further drying across the district...and periodically breezy conditions during the middle to late week period. && Slc watches/warnings/advisories... Utah...none. Wyoming...red flag warning for wyz 277 from 17z Saturday through 03z Sunday. && $$ Merrill/verzella/Kruse For more information from National oceanic and atmospheric administration/S National Weather Service visit... http://weather.Gov/saltlakecity (all lower case) For frequently asked questions about the area forecast discussion visit... http://weather.Gov/saltlakecity/general/afd_faqs.Php (all lower case)
