NWS Forecaster Discussion
930 fxus66 kmfr 212301 afdmfr Area forecast discussion National Weather Service Medford or 301 PM PST Sat Nov 21 2009 ..updated for High Wind Warning for coastal zones...Wind advisories for Shasta Valley and Lake County...and Winter Weather Advisory for snow and blowing snow over the Cascades and much of Klamath County. Discussion...quick-moving developing frontal system will impact the County Warning Area tonight through Sunday morning. The main impacts will be strong winds and some snow over the Cascades and the east side. The fast movement of this system...along with more westerly winds...will favor the Cascades receiving more snowfall and The Mount Shasta area receiving less than the previous storm. Models have settled on a 990mb low centered west of the Washington/or border late tonight. The strongest winds will impact coastal waters and coastal zones tonight...with winds affecting the Cascades through the east side late tonight through Sunday morning. Very strong 800 mb flow of 50kt is noted over northwestern portion of the County Warning Area late tonight...but stability should keep most of this area from getting advisory level winds. This situation may need to be looked at during the late afternoon. Significant snow will fall during a short period between tonight and tomorrow morning. A foot is possible in the higher terrain of the Cascades with several inches expected east of the Cascades in Klamath County. On Sunday in the postfrontal environment expect snow showers above 3500 feet and rain showers in the lower elevations. Ridging will build over the region Sunday night...essentially ending the precipitation over the County Warning Area. Models have been very persistent with upper ridging from Monday through Wednesday over northern California and southwestern or...with the resultant weather impacts being morning fog Monday through Wednesday in the favored low elevation areas like the rogue and Illinois valleys...and the Umpqua Basin. A weak warm front brushes the coast on Wednesday but will not likely result in any significant precipitation. GFS and European model (ecmwf) both put an end to the dry weather on Thanksgiving day but their solutions are still fairly different. There are still unknowns regarding the forecast for Thursday...but at this point it seems reasonable to expect light snow in the mountains and light rain in the valleys on late Thursday. It still seems there will not be a large storm for Thanksgiving day travelers in the region. && Aviation...middle clouds are streaming over the region today and will gradually lower during the day and evening. Current VFR ceilings will be short-lived as another front drops most terminals to MVFR and occasional IFR in low clouds and showers by this evening. Coastal terminals will likely be impacted by low level wind shear with gusty winds to 35kt but even stronger 50-60kt winds just above the surface. Strong winds will also impact the Cascades and the east side late tonight and Sunday morning. Mountains and east side will have snow tonight and Sunday morning...reducing visibilities. Mountain obscuration will be widespread by tonight through Sunday as deep moisture pushes into the region. && Mfr watches/warnings/advisories... or...Winter Weather Advisory from 7 PM this evening to 7 am PST Sunday for orz027-orz028-orz029-orz030. Wind Advisory from 10 PM this evening to 7 am PST Sunday for orz031. High Wind Warning until 4 am PST Sunday for orz021-orz022. California...Wind Advisory from 10 PM this evening to 4 am PST Sunday for caz081. Pacific coastal waters...Storm Warning until 4 am PST Sunday for pzz350-pzz370. Gale Warning until 4 PM PST this afternoon for pzz350-pzz370. Hazardous seas warning until 4 am PST Monday for pzz350-pzz356- pzz370-pzz376. Gale Warning until 4 am PST Sunday for pzz356-pzz376. $$ Keene
