Area Forecast Discussion National Weather Service Medford OR 620 AM PDT Sat Jun 12 2021

The Marine and Aviation sections have been updated .

DISCUSSION. Today, we'll start with a little climatology and put yesterday's rainfall and temperatures in perspective. Yesterday was unusual for Medford, at least by June standards with 0.44 of an inch of precipitation recorded at the airport for the 24-hour period and a high temperature of only 58 degrees. The high temperature was only one degree above the record lowest maximum temperature for June 11th, which was 57 degrees set back in 1950. Incidentally, a daily rainfall record was also set on June 11, 1950, with 0.65 of an inch. The 0.44 yesterday was 3rd all time for June 11. But what's really interesting is that it was 3rd because just last year on June 11, we had 0.50 of an inch of precipitation, good for second highest for the date! Does anyone remember that from last year? :)

A significant atmospheric river (AR) set up over the area yesterday in response to a strong upper jet that was able to tap into some subtropical moisture over the Pacific due to anomalous upper troughing out near 48N and 138W. One upper short wave moved through yesterday and another will round the base of the offshore trough and take aim at the coast today. We are currently in a period of short wave ridging between the 2 disturbances, so most areas will be dry and warmer today with some sunny intervals. It'll probably feel humid too due to the recent rainfall and an increase in dew points, especially west of the Cascades.

A second peak in IVT (Integrated Vapor Transport) will arrive at the coast tonight, but this time will be more directed SSW to NNE and not as far inland as yesterday's AR. This means the focus for precipitation will be along the coast and just inland, primarily west of a Highway 199 to I-5 line N&W of Grants Pass/Roseburg. In these areas through Sunday, we expect another 1-3 inches of rain, with the highest amounts in areas of coastal Curry County and also the adjacent Coast Range mountains. Farther inland, precipitation chances will diminish significantly. We probably won't see much here in Medford through Sunday morning, but there is still a slight chance to chance of showers east of I-5 during this time frame.

We expect some instability Sunday afternoon with daytime heating and higher dew points. It should be noted that model guidance is showing PW values in the 1.00-1.25 inch range, so, in addition to the rain along the coast, expect coverage of showers to expand over inland areas near and west of the Cascades in the afternoon. Model instability parameters are sufficient (850 computed LI of -2 to -3) for isolated to perhaps scattered thunderstorms and the current forecast reflects this thinking. Best chances for thunderstorms will be in the Cascades/Cascade foothills NNE across northwestern Klamath County in the afternoon/evening. Due to high PWs, any storms that do develop should be efficient rain producers. A cell or two could become strong with gusty winds/small hail, but storm motions should carry these mostly off to the north-northeast and into Portland/Pendleton's areas.

A short wave will round the base of the trough on Monday and move onshore Monday afternoon/evening. We'll be in right rear quad of the upper jet. Moisture and instability will linger, so we'll keep a chance of showers with a slight chance of thunderstorms in the forecast. Best chance of thunderstorms will be in the northern portions of the Cascades and across northern Klamath County.

One last short wave will move through the long wave trough on Tuesday, ultimately allowing the entire trough to eject east- northeastward across the PacNW and into western Canada. There can still be some showers across N&W sections of the CWA, but things should begin to dry out. This will be the last of the "cooler" days across the area. The upper ridge near the Four Corners will then assert its influence allowing heights to rise and temperatures to surge back to above normal levels mid-late next week. It probably won't take long for high temperatures to get back into the mid 90s here in Medford (Thu-Fri). -Spilde

AVIATION. For the 12/12Z TAF Cycle . Lots of IFR to LIFR in low clouds and fog exists across the valleys of the west side as of 615 AM PDT this morning in the wake of yesterday's significant rainfall. While mountain areas are mostly obscured this morning, lee side drying under a general southwest flow has opened up some clear areas already across much of the middle of the forecast area and some of the east side. Conditions are likely to improve to VFR for all valley locations late this morning, though MVFR could linger into the afternoon along and near the coast and partial mountain obscurations should generally be expected. A new frontal system is expected to push onto the coast and to about as far as the Cascades late this afternoon into this evening with showers. Areas west of KRBG and Grants Pass are likely to get some rain late this afternoon through tonight with MVFR to IFR conditions expected. ~BTL

MARINE. Updated 300 AM PDT Saturday, 12 June 2021 . Steep, advisory level seas will continue to gradually subside with time from southeast to northwest this morning. Southerly winds will then increase this afternoon into this evening as a new front moves in from the west. This will bring more rain as well as another period of advisory level conditions this evening through much of Sunday. A period of relatively calm conditions is then expected Sunday night through Tuesday. High pressure is likely to develop a thermal trough along the coast Wednesday persisting into next weekend. This is likely to result in gusty northerly winds and building seas, especially south of Cape Blanco. Gales will be possible for portions of the area south of Cape Blanco in the afternoon and evening hours as early as Wednesday into the following week. ~BTL
