12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Area Forecast Discussion National Weather Service Medford OR 244 PM PDT Wed Aug 5 2020
DISCUSSION. A 18z sounding from the IMET on the July fire complex showed similar instability and lapse rates to the model data, but the shear was 5kt higher for all elements. This increases confidence that any thunderstorms in Modoc, Lake, and eastern Klamath Counties will be capable of producing hail nearing one inch. These storms could also have strong outflow winds with them as well. Siskiyou County is still not showing an environment as capable of the one inch hail, but pea sized hail should be anticipated with any thunderstorm.
Thursday morning, increased QPF along the coast by a few hundredths, so areas from Coos Bay north could see up to one tenth of accumulation, with areas from Port Orford north receiving around 0.05" of accumulation. The front looks to hold together more than has been shown the past few days, so northern Douglas County could also observe a few hundredths of rain. However, it is more likely this will result from accumulating drizzle and be contained more to higher elevations in the mid-morning. The front will also bring strong west winds along and east of the Cascade crest.
Following this, the weather mellows out onshore, but a strong thermal trough takes up over the marine waters and is likely to cause gale force winds. Offshore flow looks modest with easterly 850 to 825 mb winds around 20 to 25 knots. Temperatures will warm into the new week for the whole area. Highs are expected to hit 99 on Monday in Medford with 106 expected in Happy Camp and Somes Bar. No heat related advisories are anticipated at this time, but if overnight lows continue to warm as the afternoon highs have, a short duration advisory may be considered.
There are indications of a trough returning early next week. Most solutions maintain an open wave pattern and the GFS deterministic has backed off on showing a cutoff low. We will monitor for trends towards a cutoff low pattern as it is favorable for thunderstorms, but for now have excluded them from the forecast. -Miles
AVIATION. For the 05/18Z TAF Cycle . IFR/MVFR ceilings at the coast and in the Umpqua Basin will clear by early afternoon to VFR. We expect IFR conditions (perhaps low MVFR) to return to the coast/coastal valleys around 02Z and then reach the Umpqua Valley and KRBG by around 09z, but the KRBG ceilings could be a low VFR ceiling around 3500 feet. An approaching cold front will bring a chance for showers to the coast Thursday morning.
Elsewhere, inland areas will have breezy conditions this afternoon, and VFR conditions are expected except over and near the Scott Valley and areas east of the Cascades this afternoon into this evening. In those areas isolated to scattered thunderstorms-some of which could be strong or even severe-are expected. These thunderstorms will be capable of gusty outflow winds and, possibly, micro-bursts. Thunderstorms are possible at KLMT this afternoon, but those should move east of there by evening.
Over southwest Siskiyou County near the Red Salmon Fire there's likely to be some local MVFR visibility restrictions due to smoke. ~Keene/BTL
MARINE. Updated 230 PM PDT Wednesday, 5 August 2020 . A borderline Small Craft Advisory event continues south of Port Orford and beyond about 3 NM from shore, with north winds 20 to 25 kt and seas around 6 ft. Winds and seas will weaken tonight as a cold front moves through.
The thermal trough will then re-strengthen Thursday afternoon bringing the return of advisory level conditions south of Cape Blanco. Friday through the weekend winds and seas are likely to strengthen further with advisory level winds and seas expected to expand to areas north of Cape Blanco by Saturday. Gales are likely for a portion of the area south of Cape Blanco with advisory levels winds and seas expected for all areas south of the Cape. It should be noted that Friday through early next week could be a prolonged upwelling event for the coastal waters with multiple consecutive days of hazardous conditions. Keene/BTL
FIRE WEATHER. Updated 230 PM PDT Wednesday 5 August 2020 . The main concern in the forecast period will be scattered thunderstorms late afternoon into the evening. Scattered coverage is expected in portions of the east side in Oregon, and western Siskiyou county.
The upper trough is moving inland in northern California. Instability, mid level moisture and trigger will be higher east of the Cascades and Western Siskiyou county, and a Red Flag warning is in place for these areas.
Thursday, the upper trough shifts east and any threat of storms will be east of the forecast area. Temperatures will be cooler and relative humidity higher, however gusty winds are expected in the afternoon due to a combination of a stronger winds aloft and tightening pressure gradient.
Friday through next weekend should remain dry with a thermal trough developing along the coast with increasing east to northeast winds near and at the ridges in fire zones 618, 619 and western 280.
The operational run of the GFS is showing an upper low deepening of the coast of Central California early next week, with instability in northern California Monday and Tuesday. However, most models are not showing this, and have not added this at this time. This will be something to focus on as we approach this time period. -Sven
