Next chance for widespread rainfall continues to be tied to a shortwave which breaking from a stalled low over the Pacific NW/British Columbia. This shortwave is shown breaking away and making eastward progression around Wednesday before reaching the area late in the week. Models continue to have slight differences in timing, but the ongoing trend of slowing the system seems to be winning out. The result is the impacts of this shortwave would likely not be felt until late Friday, or more likely Saturday as advertised in the ECMWF over the past several days. When this shortwave approaches the area, it should send a cold font across the forecast area with preceding showers. && .AVIATION...(For the 00Z TAFS through 00Z Tuesday Evening) Issued at 740 PM EDT Mon Mar 30 2020 VFR to start expected to dwindle back into MVFR cigs again late tonight in response to some increase in low level thermal trough as nrly flow deepens ahead of backing disturbance dropping through lower MI.
