Area forecast discussion...updated National Weather Service Salt Lake City Utah 408 PM MDT Thursday Jul 30 2015 Update...added isolated mention of thunderstorms to about the southern 1/4 of the County Warning Area for the rest of this afternoon and this evening as the moisture over southern Utah has set off a few small cells over Washington Colorado and near Lake Powell that are not tied to the terrain. Expect this activity to expand a bit through early evening then tend to diminish. There is a possibility that a few of these could persist overnight as the deeper moisture to our S continues to seep north. && Synopsis...a ridge of high pressure will remain over the region through the end of the week...then shift eastward early next week. Moisture will slowly increase across southern Utah through Friday...then spread slowly northward late in the weekend. && Discussion...an upper-level ridge axis extends from the Southern Plains westward through Utah and Nevada into northern California. Return flow around the ridge has lifted precipitable waters above 1.0" over areas southwest of this axis...including far southern Utah...but conditions are much drier further north. This afternoon and evening...isolated showers and storms are expected over the higher terrain across the south while clear skies prevail elsewhere. This setup will persist through Saturday as an approaching cutoff low offshore gradually turns flow more southerly and allows moisture to creep northward over the southern half of the County Warning Area. On Sunday...both the ec and GFS develop a vorticity maximum over southern Utah in an area of enhanced convection. While the GFS hints at this feature propagating into northern Utah and increasing probability of precipitation somewhat...the ec seems to go too far with its development. For now...the forecast leans toward drier conditions given low confidence. Next week...models are struggling to resolve the timing and phasing of a cutoff low along the California coast an upper-level trough dropping southward off the British Columbia coast. The ec solutions results in a more westerly flow component whereas the GFS builds a ridge and very warm temperatures overhead. Both cases suggest primarily dry conditions over northern Utah...but the GFS solution would allow for moisture to creep into the southern County Warning Area and aid in convection south and east of the mountains. && Aviation...northerly winds will prevail at the slc terminal through around 04z before returning to southerly. Otherwise...expect VFR conditions under mostly clear skies through the night. && Fire weather...the potential of isolated high based thunderstorms and dry lightning will increase through the upcoming weekend from south to north. Moisture currently along and south of the Utah/Arizona border will gradually spread north beginning Saturday ahead of a developing weak disturbance that will move through the district Sunday into Monday. Moisture is expected to remain primarily at the middle and upper levels during that time owing to the potential of some dry lightning strikes and a high likelihood of gusty winds with any storms that form. Areal coverage of these isolated storms is expected to be greatest Sunday into Monday. Southwesterly flow aloft will spread in behind this disturbance Tuesday allowing both a further drying trend and a net increase of southerly surface winds for the middle week period. && Slc watches/warnings/advisories...
