KMAX showing MARC signature at 12000 feet MSL with the SVR warned storm. Also had a 0.50 inch hail report via SHAVE from the warning polygon where MESH indicated 0.50 inch.

Storms in the MRF CWA show decent cores around the freezing level but struggled to get anything into the hail growth zone. MESH was monitored to any intensification. Interesting report came in from EKA office, maybe 50-75 miles south of the MFR CWA of penny hail, shown below.
An attempt was made using MESH and All Tilts to figure out what led to this report. MESH didn’t show much, neither did All Tilts. Both teams were unable to discern for sure if beam blockage played a large role in how paltry the storm in the area of the report looked.

Bill/Jenni team observe MESH gone up dramatically on storm of interest. Shouldn’t last long but will go with a short duration SVR.

Bill/Jenni close to warning thresholds associating mesh with hail reports on NW storm with 60+ dBZ. Using FSI to get a cross section and look at CAPPI.

Group splits into 2 groups of 2. Were going to have one group be Medford and the other Eureka, however in the time it is taking to compose this, Eureka looks pretty poor. So both will be Medford. We’ll ride this for as long as we can with such a rare opportunity to see svr in this area.

Setting the floater domain to N. CA/S. OR. Main domain for OUN will still be able to capture the stuff in SJT/LUB. Still good storms in SJT/LUB and several warnings have been issued by EKA in N. CA. Dinner break until 5:30, then will do IOP for EKA and/or SJT/LUB.

LMA discussion: Pete noticed that even though VIL was decreasing on a particular storm near KDOX, LMA showed a steady increase and in general his thought was that the storm was intensifying overall and worthy of a warning. He liked the LMA trend graphs.

All forecasters are checking out PHI/LWX CWA’s LMA data in realtime. Storms in the blue box have had a marginal threat of severe winds. Keeping an eye on Medford’s CWA and the quasi-supecellular storms in the LUB CWA. May make a switch around 430 PM or after dinner.
