Area Forecast Discussion National Weather Service Medford OR 807 PM PDT Sun Jun 20 2021

DISCUSSION. 21/00Z NAM in.

Lots of marine stratus over the coastal waters and along the coast this evening. Mostly clear skies prevail over the inland areas, except for a band of now dissipating cumulus clouds extending from western Siskiyou county northeast into central Lake county. Much cooler along the south coast this evening. Brookings only made it to 65 degrees today after peaking at 98 degrees Saturday. Winds over the coastal waters have diminished quite a bit as well.

The cooler temperatures and lower winds along the coast occurred because a thermal trough just off the coast moved inland Sunday. This supported quite a warm up over the inland areas with high temperatures 15 to 20 degrees above normal for this time of year. Monday will also be quite hot with highs similar to the Sunday highs for most locations.

Overnight lows will not fare much better, and some areas may not drop below 70 degrees overnight. As a result, an Excessive Heat Warning remains in effect for the inland west side valleys, except for the Umpqua Basin, through Monday. For details see PDXNPWMFR.

The pattern will change Monday evening into Tuesday as an upper low develops off the California coast and the thermal trough weakens. Temperatures will cool off a bit, and mid to upper level southerly flow east of the low will advect moisture into the area. This, combined with strong surface heating and instability aloft introduced by short waves rotating around the low, will create a classic thunderstorm pattern for the Medford forecast area. The upper low will drift north to northeast Monday through Wednesday, getting closer to the Medford forecast area. This will make for a long lived event, lasting from Monday evening through Wednesday afternoon.

The next challenge is the timing and location of convection during this interval. Model lifted indices show instability developing Monday afternoon over the Cascades and higher terrain of the east side with the most unstable area around Chemult, which is a favored location for thunderstorm development. While thunderstorms will most likely develop along the ridges, they will move over the adjacent valleys once they do form, and the steering flow will be southwest to northwest. The current forecast reflects this thinking.

The air mass will remain unstable Monday night despite the loss of surface heating and at least isolated thunderstorm coverage will persist through the night east of the Cascade crest.

Tuesday looks to be the most active day with widespread instability over most of inland areas of the Medford forecast area supporting isolated to scattered thunderstorms. The exceptions will be the Umpqua Basin and eastern Siskiyou and Modoc counties.

On Wednesday, the lessening surface heating will make for a more stable air mass. Thunderstorm activity will be isolated in nature, and the model lifted indices indicate the greatest instability will be over the Siskiyous and Cascades as well as the Kalmiopsis.

It now appears that the upper level low will not open up and move inland Thursday, but rather it will drift south as ridging develops to the north. As it moves south, the flow aloft will become east to northeast and this will cut off the moisture source for convection. This will bring the an end to thunderstorm chances. Upper level ridging will return along with the offshore thermal trough, and next weekend looks to be hotter than today was and tomorrow will be over inland locations.

AVIATION. For the 21/00Z TAF Cycle . LIFR and IFR ceilings and visibilities are impacting the coast and into Coos Bay. These low ceilings are expected to surge into the Coquille Valley overnight. Then, the edge of the stratus will erode back to the beaches during Monday morning. Elsewhere, VFR conditions are expected through Monday evening. But, cumulus will develop Monday afternoon over the higher terrain from the Siskiyou Mountains and Cascades eastward with isolated to scattered thunderstorms developing during the evening. -DW

MARINE. Updated 800 PM PDT Sunday 20 June 2021 . Winds gradually diminish but seas remain steep tonight into Monday afternoon as the thermal trough moves farther inland. Light, near shore southerly winds develop south of Brookings late tonight and spread to Cape Blanco by Monday evening. Seas are expected to lower below small craft levels by late Monday afternoon and remain low into Tuesday.

Northerly winds increase Wednesday afternoon with strongest winds near Cape Blanco, but speeds are not expected to reach advisory strength. But on Thursday, possibly continuing into Friday, small craft advisory level conditions are likely across much of the waters with stronger north winds and a fresh northwest swell. Uncertainty increases beginning Friday with stronger northerly winds possibly reaching gale force during the weekend. -DW

FIRE WEATHER. Updated 800 PM PDT Sun 20 Jun 2021 . Instability will increase Monday with a scattered thunderstorms possible in portions of the southern Cascades to the east side of Oregon. A Red Flag Warning is in effect for the area for Monday afternoon into Monday night. Thunderstorms will continue into Tuesday morning. The upper low will move closer to the region just off the coast of northern California Tuesday, and will continue to feed moisture into the region. This will result in more thunderstorms from Western Siskiyou county, and up the Cascades and across the east side. There may be scattered thunderstorms in places, mainly western Siskiyou county, the Cascades, and east of the Cascades. A fire weather watch has been issued for this area for Tuesday afternoon and evening. There will also be thunderstorms Wednesday, but coverage will be isolated. An upper ridge will build toward the end of the week and near record high temperatures are possible next weekend.

MFR WATCHES/WARNINGS/ADVISORIES. OR . Red Flag Warning from 5 PM Monday to 3 AM PDT Tuesday for ORZ623>625. Fire Weather Watch from Tuesday afternoon through Tuesday evening for ORZ621>625. Excessive Heat Warning until 11 PM PDT Monday for ORZ024-026.

CA . Fire Weather Watch from Tuesday afternoon through Tuesday evening for CAZ280-281. Excessive Heat Warning until 11 PM PDT Monday for CAZ080>082.

Pacific Coastal Waters . Small Craft Advisory until 2 PM PDT Monday for PZZ350-356-370-376. Gale Warning until 11 PM PDT this evening for PZZ356-376.
