624 FXUS66 KMFR 270528 AFDMFR Area Forecast Discussion National Weather Service Medford OR 1028 PM PDT Wed Jun 26 2024 .DISCUSSION...A cold front has moved through the region with temperatures notably cooler compared yesterday. Here at the airport, temperatures are 17 degrees cooler than this time last night. WPC has plotted another cold/occluded front offshore this evening and that should be pushing into the region through tonight with temperatures lowering a few more degrees. Nothing impactful to the population or the region at large tonight. There could be some more drizzle near the coast with some weak lift and a moist boundary layer. On a more interesting note, there was some blowing dust observed on satellite earlier this afternoon near Summer Lake. This really shows how dry and windy it was earlier this afternoon. -Smith .SHORT TERM.../Issued 259 PM PDT Wed Jun 26 2024/ A line of higher clouds are moving northeast into more of Douglas and Josephine counties this afternoon. The stratus is still present at the coast and into the Umpqua Basin. and will continue tonight. Winds are strong this afternoon with gusts near 25-35 mph this afternoon and high profile vehicles will have difficulty driving. A cold front is passing today. Drizzle and light rain, less than a tenth of an inch, is possible tonight near the coast and into northern Douglas County. This front will bring a cooldown to near normal temperatures east of the Cascades with slightly below normal temperatures west. This translates to mostly 70s and low 80s with 60s at the coast. Tonight will also be a colder night east side with lows in the 30s again. Chemult has a 70-80% probability to see temperatures fall to or below 36 degrees tonight. Northerly winds will continue tomorrow and early Saturday and will not be as breezy as the winds today. Temperatures will be slightly warmer Friday afternoon with highs near 80 east of the Cascades and some upper 80s in the Rogue Valley. Hermansen .LONG TERM.../Issued 259 PM PDT Wed Jun 26 2024/ Saturday through Tuesday...Models are consistent in timing another marine push into the west side here later Saturday or Saturday night with west side marine clouds and possibly some additional coastal drizzle. Thereafter the common theme is warming weather under building high pressure and stable conditions next week. NBM shows chances of exceeding 90 in Medford increasing from only 38% Tuesday to 58% Wednesday, then to above 60% Thursday through Friday. Stavish && .AVIATION 27/06Z TAFS...

Marine moisture is sustaining low ceilings along the Oregon coast, with MVFR levels over North Bend and IFR ceilings over Brookings. Ceilings will likely remain at MVFR or IFR along the coast overnight, with low chances (10-20%) of drizzle north of Cape Blanco. Areas of drizzle may locally lower visibilities, so extra caution is encouraged. Marine clouds should clear up as the upper trough moves to the east. Inland areas will stay VFR through the TAF period, as any clouds that do develop will not affect flight levels. -TAD

&& .MARINE...Updated 815 PM Wednesday, June 26, 2024...Relatively calm seas under light winds and gentle westerly swell are expected to continue through Thursday. Gusty north winds will return Thursday afternoon, with steep seas and advisory level conditions returning south of Cape Blanco by Thursday night. Another front and deep marine layer are likely to disrupt the pattern this weekend, with improved conditions expected Saturday and Sunday. -TAD && .FIRE WEATHER.../Issued 259 PM PDT Wed Jun 26 2024/ Red Flag conditions being observed this afternoon across much of the east with sites gusting 30-40 mph and RHs into the 10-15% range. Winds are going to be on the decrease tonight. Thursday morning more marine clouds will push into the west side with some possible scattered coverage through early morning over the Rogue Valley and banked into the Siskiyous. Later Thursday through Friday should see a short warming/drying trend before another weak trough passage and marine push by mid to late weekend. This event shouldn`t cool the temperatures too much. Thereafter next week looks to be a fairly high confidence warming and drying event. Some red ERC numbers are showing up toward Thursday and Friday in the GACC`s 10-day projected table indicating values reaching or exceeding the 95th percentile.
