NWS Spokane, WA wrote its last area forecast discussion before the first event at Jun 3, 3:42 PM PST, 3 hours 23 minutes earlier.
Area Forecast Discussion National Weather Service Spokane WA 442 PM PDT WED JUN 3 2015 .SYNOPSIS... Overall a decreasing threat of showers is expected into Thursday...becoming confined to mainly the northern mountains. Much warmer weather is expected Friday into the weekend as a high pressure ridge returns to the region. Saturday, Sunday and Monday will feel like summer, with afternoon temperatures in the mid 80s to mid 90s. && .DISCUSSION... Tonight and Thursday...A closed low over southeast British Columbia will slowly migrate into Alberta through Thursday. The low will remain in close enough proximity to generate isolated/scattered shower activity over the region mainly during peak heating (afternoon and early evening) with the highest coverage over the mountains near the Canadian border where the highest low level moisture resides and also due to closer proximity to the closed low. Cloud cover will continue to limit instability potential with models only showing CAPE values of 200-500 J/KG mainly over the northern mountains through early this evening and again on Thursday. There is also a secondary area of stronger instability over NE Oregon and the Clearwaters clipping the Blue Mtns, Camas Prairie, and Central Panhandle Mountains through early this evening. Given marginal instability for thunderstorms any storm that occur are expected to be short lived. JW Thursday night through Saturday...Models are in generally good agreement regarding the upper level field of motion for the next few days. Another Pacific trough will be digging into California and the Great Basin on Thursday with a residual northern branch wave remaining over British Columbia...and then by Friday the Great Basin system pinches off into a broad closed low while the forecast area will experience a building positively tilted ridge. This ridging will effectively stabilize the region and lead to an end of any thunder threat after Thursday's convection dies down after sunset. Through Friday and Saturday this ridge will dominate and manifest itself as a strong warming and drying trend. Temperatures will progressively increase each day with plenty of sunshine. Temperatures will achieve generally 80s readings by Friday...and then mid to upper 80s on Saturday with a few low 90s readings in the lowest elevations by Saturday afternoon. In a nutshell...the next 72 hours will feature a transition period from the unsettled and showery regime of the past week...to a dry and summer-like and eventually very warm pattern. /Fugazzi Saturday night through Wednesday...Positively tilted ridge of high pressure noses into the region and shows some minor amplification until a trof dropping down through British Columbia flattens it out some Monday night. This allow for a drying and warming trend with temperatures peaking on Monday. Monday night and beyond some hint of high pressure remains but the pattern over the western US seems to be more of a split flow low index pattern. Ensemble tables suggest precipitable water values remain high with standard anomalies running two standard deviations on the wetter side of what would be considered normal. With that said it seems likely mesoscale and smaller interaction during the peak heating of each of those days could allow for some minor pulse shower and thunderstorm development in the afternoons and early evenings.. /Pelatti && .AVIATION... 00Z TAFS: A filling trof of low pressure remains over the region for one more day. Broken ceilings will slowly become scattered this evening. Heating Thur morning will bring another sct-bkn deck of strato-cumulus ranging frm 4-6K ft AGL. Drier air begins to move into the region aft 20z promoting a decr trend in bkn ceilings. As for precipitation...isolated -shra possible with peak heating in the northern and eastern mountains with little impact to main terminals. /sb && .PRELIMINARY POINT TEMPS/POPS...
