Wednesday is Groundhog Day! Will “Phil” see his shadow in the snow? We’ll talk about the groundhog report tomorrow.

________________

The jet stream shows a high pressure ridge ( “arch” shaped area) aiming the airflow straight South toward the Pacific Northwest. That cleared the skies and allows for colder nights, but lots of  daytime sunshine. Remember that, particularly this time of the year, when it’s not raining it is usually fogging and we’ve had some pretty dense fog lately.

Advisories: A FREEZE WARNING IS IN EFFECT FROM MIDNIGHT TONIGHT THROUGH 8 AM WEDNESDAY  FOR THE SOUTH CENTRAL OREGON COAST. AN AIR STAGNATION ADVISORY IS IN EFFECT UNTIL 10 AM SATURDAY FOR CENTRAL DOUGLAS COUNTY INCLUDING ROSEBURG, EASTERN CURRY COUNTY, JOSEPHINE COUNTY, JACKSON COUNTY, THE KLAMATH BASIN, NORTHERN AND EASTERN KLAMATH COUNTY, AND CENTRAL, EASTERN, AND WESTERN LAKE COUNTY.
