SHORT TERM. Today through Saturday. Mainly clear skies across the region early this morning with mild temperatures and light winds. Expect sunny skies through the morning then becoming partly cloudy in the afternoon. Southerly flow aloft continues with a fair amount of low and mid level instability. Water vapor imagery showing a weak short wave moving northward across California. This will likely result in scattered thunderstorms later this afternoon and evening over central Oregon. Models are in good agreement on this scenario. The storms should dissipate in the late evening hours with partly cloudy conditions overnight. Similar pattern on Friday although the approaching short wave will be stronger. Expect thunderstorms to develop in the afternoon over central Oregon. These will continue into the evening then dissipate. By Saturday a deeper plume of moisture will be over the area and will likely result in more widespread showers and thunderstorms. Hot temperatures the next few days with 850mb temps 25-30C. This will give 90s to 102 today and upper 90s to 107 Fri. Sat temperatures will be more dependent on increasing cloud cover. Will likely end up with cooler temps and higher humidity as dew points approach 55-60 degrees. 94
LONG TERM. Sunday through Thursday . Ensemble means continue to be in good agreement. However, they do begin to diverge in their handling of the retreating upper level ridge and the strengthening low off the BC coast. The ECMWF weakens the ridge quicker and moves it westward to southern CA/western AZ while the GFS keeps it stronger and a little farther east. This results in a more southerly component in the upper level flow across the CWA with respect to the GFS, especially by mid-week. If this pans out, some drier air may filter into the area reducing our chance of mountains showers or thunderstorms by Thursday. As the high PWATs push east of the area Monday or Tuesday we'll begin to see more normal values over the area. In the interim, Sunday should be the last day of widespread precipitation, especially over our eastern CWA. Deterministic models show a nice disturbance moving through the area during the afternoon which should enhance convective activity, especially over our eastern CWA. Very heavy rainfall could occur with the stronger storms, especially if the slower ECMWF solution pans out. Areal coverage, mainly over the mountains, will decrease each day as the atmosphere continues to dry out.
Daytime highs are expected to finally drop to near normal values through much of next week. However, there are enough differences in the ensemble members to warrant a nudge to slightly above normal, especially if the ECMWF is correct. Earle
AVIATION. 12Z TAFS . VFR conditions will prevail through the period. Isolated thunderstorms are expected to develop over Central Oregon and along the OR Cascades. At this time, none of these storms are expected to affect KRDM or KBDN. Some mid/high level clouds will continue through the period. Winds will be 5-12 kts with higher afternoon gusts. Winds will decrease overnight. Earle
