Area Forecast Discussion National Weather Service Medford OR 809 PM PDT Sat Jul 4 2020
DISCUSSION. Sunny and hazy skies continue over the forecast are today. Wildfire smoke from Siberia is likely still contributing to some reduced air quality today. Clouds will make their way inland from the coast tonight, likely filling in at the coast, coastal valleys, and Umpqua Basin late tonight and early Sunday morning. These clouds will clear by middle to late Sunday morning, and temperatures Sunday will be very similar to today, right around normal for this time of year.
No changes to the forecast are expected this evening. Please see the previous discussion below for more details on the continued quiet weather pattern.
AVIATION. For the 05/00Z TAF Cycle . VFR will continue through Sunday evening south and east of the Umpqua Valley. Otherwise, another marine push is expected tonight with MVFR ceilings returning to the coast north of Port Orford around 07z, spreading into the Umpqua Valley around 11z. Similar to today, the stratus will gradually gradually erode Sunday morning. -DW
MARINE. Updated 800 PM PDT Saturday, 4 July 2020 . Relatively light winds and low seas are expected this weekend. However, a low long period south swell will build into Sunday. Waves breaking farther from shore could result in problematic bar conditions. This will also bring an increased sneaker wave risk, especially south of Cape Blanco. Of note, after days of significant upwelling, water temperatures from Port Orford to the Point Saint George Buoy 27 continue to range from 45 to 48 degrees Fahrenheit.
The thermal trough will return next week, but models are showing it taking up a more inland position. This would keep north winds in place over the area, but at a weaker strength than during a typical event.
FIRE WEATHER. Updated 200 PM PDT Saturday, 4 July 2020 . No lightning was observed yesterday, July 3rd, 2020.
West and northwest winds are on track to be breezy and gusty this afternoon and evening, generally 7 to 15 mph with gusts 15 to 25 mph. They should be on the down swing by 8PM PDT except in places with local effects for later evening winds such as Summer Lake.
With the overall weather pattern changing very little this week, we're not expecting much in the way of day to day changes, overall. However, shortwave impulses and related mostly dry cold fronts Monday and Thursday are both likely to drive the most appreciable weather changes of the week. These will bring with them inland surges in the marine layer, increased and gusty winds, and slightly cooler weather behind them. There also is a slight chance of thunderstorms in NE Lake County late Monday afternoon into early Monday evening.
For Thursday, July 9th both the ECE and GEFS continue to indicate a somewhat stronger shortwave trough and front moving through with the GEFS suggesting some precipitation potential across the northwestern portion of the forecast area. The main effect is likely to be another cool down, more marine layer over NW sections of the area, and some gusty winds. The tail end of this trough is expected to linger through about July 12th.
Thereafter, both the ECE and the GEFS continue to indicate temperatures are most likely to go above normal through the end of the month. This is notable because late July through early September are typically the core of both our wildfire and smoke season in the Medford NWS forecast area. ~BTL
PREV DISCUSSION. /Issued 214 PM PDT Sat Jul 4 2020/
DISCUSSION . Long wave troughing will remain over the PacNW for the remainder of the weekend and well into next week. This will keep the area under near to slightly below normal temperatures with largely dry conditions and breezy afternoons. Expect the nightly return of marine stratus along the coast, especially north of Cape Blanco, and into the Umpqua Basin. These clouds will linger into the morning hours, but will give way to sun in the afternoons. Overall, changes in the day to day weather will be subtle and anything more notable will be due to shortwave troughs moving through the larger scale trough at times during the upcoming week.
One such shortwave trough is expected Monday into Tuesday. For most of the area, this trough will bring a slight cooling trend with some enhanced afternoon breezes. However, there will be enough moisture and instability along with a trigger to warrant a slight chance of thunderstorms for the northern portions of Klamath and Lake counties Monday afternoon. Another weak disturbance will move through on Tuesday and this could bring a chance for some light showers along the coast from North Bend northward.
Another, potentially stronger, shortwave trough is expected to pass through the area Thursday. Models continue to vary in the strength of this trough and whether it will deliver any precipitation to area. The EC and it's ensembles keep the area dry except for the immediate coast north of Cape Blanco. The GFS and it's ensembles are a bit more ambitious with precipitation, but even the wettest solutions only bring a few hundreths at best to coastal areas. Given the differences here, have leaned on the National Blend of Models for the forecast, which brings some slight chances for precipitation along the coast north of Cape Blanco and along the Cascades north of Crater Lake. As for any thunderstorm potential with this trough, current parameters look to be too stable in our area for thunderstorm concerns. The better area of moisture and instability looks to north and east of the area. However, will continue to monitor for any changes. /BR-y
