A developing winter storm will track across the Mid-Atlantic and Northeast Sunday and Sunday night. Meanwhile, arctic air continues to dive southward across the center of the nation and will spread eastward into the new week. Cold temperatures and strong winds will result in dangerous low wind chill values for locations along and east of the Rockies. For southern California, Santa Ana winds return Read More >
.AVIATION... 06Z TAFS: Areas of low clouds and patchy freezing fog will impact the Spokane/CdA area into the upper Columbia Basin, with a moisture boundary layer and light winds. This will impact GEG/SFF/COE with MVFR to IFR conditions, with GEG the best potential to see IFR conditions tonight/early Sunday. A drier north to northeastern flow favors improving CIGS and VIS after 17-21Z and into Sunday evening. The remaining TAF sites are expected to be VFR. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence in VFR conditions at EAT/MWH. Moderate confidence in MVFR conditions at SFF/COE through Sunday morning. Moderate confidence in IFR conditions at GEG, with low to moderate confidence in LIFR. Moderate to high confidence in VFR conditions at LWS/PUW. Yet some guidance suggest a possible brief period of migratory MVFR conditions at LWS/PUW between 18-03Z, but confidence is low. A few flurries may slip by the ID/WA border but confidence is low. ----------------------- Confidence descriptors: Low - Less than a 30 percent chance Moderate - 30 to 70 percent chance High - Greater than a 70 percent chance &&
