Forecast Discussion

608 FXUS66 KMFR 191206 AFDMFR Area Forecast Discussion National Weather Service Medford OR 506 AM PDT Fri Apr 19 2019 .Updated Aviation Discussion. .SHORT TERM... The big story for today is the potential for thunderstorms across northern California and southern Oregon. There will be potential instability in the air with a cold front approaching from the northwest. Therefore, we feel pretty good about some thunderstorms popping up around Mt Shasta and areas east of the Cascades. Storm formation will likely occur after 2pm and during the early evening hours. These storms are not expected to be exceptionally strong, so just look for small hail and perhaps some wind gusts up to 45 mph. The chance for rain showers will continue through the night as the the cold front pushes through Oregon with the system aloft also digging into Oregon. Temperatures will cool down Saturday with highs in the lower 60`s for the valleys west of the Cascades. The chance for thunderstorms on Saturday is really diminished after looking at the potential instability across the region. Therefore, it`s looking more like widespread showers with a snow level around 6500 feet. Models have been really aggressive with the amount of precipitation these showers will dump east of the Cascades. Adding up the precipitation Friday and Saturday, the majority of areas east of the Cascades will see about 0.5 inches of rain. Mt Shasta City and Summer Lake will see up to 1 inch of rain. Areas along the coast will only see a few tenths, which is unusual given that the coast is usually wetter than the eastside. After this low passes through, we`ll see a high pressure build and a thermal trough develop along the Oregon coastline. Overall, Sunday should be rather pleasant with plenty of sunshine and temperatures in the lower 70`s over the westside valleys. -Smith .LONG TERM.../Issued 320 PM PDT Thu Apr 18 2019/ Monday, Apr 22nd through Thursday, Apr 25th, 2019...
