Here is my weekly weather quiz question for the last time. “What is a “Red Flag Warning?” Here is the correct answer A Red Flag Warning is a term used by fire-weather forecasters to call attention to limited weather conditions of particular importance that may result in extreme burning conditions. It is issued when it is an on-going event or the fire weather forecaster has a high degree of confidence that Red Flag criteria will occur within 24 hours of issuance. Red Flag criteria occurs whenever a geographical area has been in a dry spell for a week or two, or for a shorter period , if before spring green-up or after fall color, and the National Fire Danger Rating System (NFDRS) is high to extreme and the following forecast weather parameters are forecasted to be met:
1) a sustained wind average 15 mph or greater
2) relative humidity less than or equal to 25 percent and
3) a temperature of greater than 75 degrees F.
In some states, dry lightning and unstable air are criteria. A Fire Weather Watch may be issued prior to the Red Flag Warning.

Here is my weekly weather quiz question for the last time. “What is a “Rear Flank Downdraft?” Here is the correct answer. A Rear Flank Downdraft is a region of dry air subsiding on the back side of, and wrapping around, a mesocyclone. It often is visible as a clear slot wrapping around the wall cloud. Scattered large precipitation particles (rain and hail) at the interface between the clear slot and wall cloud may show up on radar as a hook or pendant; thus the presence of a hook or pendant may indicate the presence of an RFD.

Here is my weekly weather quiz question for the last time. “What is a “Rear Flank Downdraft?” Here is the correct answer. A Rear Flank Downdraft is a region of dry air subsiding on the back side of, and wrapping around, a mesocyclone. It often is visible as a clear slot wrapping around the wall cloud. Scattered large precipitation particles (rain and hail) at the interface between the clear slot and wall cloud may show up on radar as a hook or pendant; thus the presence of a hook or pendant may indicate the presence of an RFD.

An Upper Level Low Pressure Trough (“U” shape) sitting right over the Pacific Northwest. The graphics for days 1-3  show a frontal system sliding into the Pacific Northwest today. The graphics for days 3-7    Tuesday through Saturday show the frontal system moving across the Pacific Northwest Tuesday, then another front offshore that pushes in between Thursday and Friday. A frontal system will be poised offshore next Saturday.
