Area Forecast Discussion National Weather Service Medford OR 904 PM PDT Mon Jul 13 2020

UPDATE. Except for some low clouds developing on the coast from Cape Blanco up to the Coos Bay area skies are generally clear across the region. This area should see the greatest cloud cover, as well as southern Coos county up against the Umpqua Divide by morning. Current forecast looks on track and will not update this evening. Sven

AVIATION. For the 14/00Z TAF Cycle . VFR conditions will prevail into this evening with gusty, breezy afternoon and evening winds, strongest near the coast. Brief periods of LIFR are possible along and near shore from Cape Blanco northward late this evening into Tuesday morning as the marine layer wobbles near the shore. -Miles/Schaaf

PREV DISCUSSION. /Issued 252 PM PDT Mon Jul 13 2020/

DISCUSSION .

The biggest story for this week and probably most of next week will be the abnormally warm temperatures as highs push into the mid 90's and up to 100 degrees in some of our northern California valleys. We evaluated the heat risk on Wednesday and it appears that overnight lows are cool enough in addition to high temperatures just not being warm enough to warrant a heat advisory on Wednesday. High temperatures will also push into the lower 80's around Brookings as offshore flow will be strong under this thermal trough.

After Wednesday, our concern then shifts to the potential for thunderstorms around Modoc County. Thunderstorm probabilities remain low around 10 to 15 percent. Potential instability is also on the low side and models are only showing 100-200 j/kg of CAPE. Analyzing the 500 mb chart is also a bit of a mess. It looks like there is a very large closed low or multiple closed lows off the California coastline on Wednesday night into Thursday. Also, a strong short wave should be moving through northern California around Thursday. The shortwave should provide enough forcing to get things going if the moisture is present. Given the lack of moisture and low thunderstorm probabilities, we'll say storms should be rather isolated if they even form at all.

A deeper long wave trough will move through the area on Sunday, yet temperatures will remain warmer and a few degrees above normal. The days to watch in the extended forecast will be next week Tuesday and Wednesday as we have a 100% chance to exceed 90 degrees and a 50% chance to exceed 100 degrees in the Rogue Valley.

MARINE . Updated 215 PM PDT Monday, 13 July 2020 . A thermal trough will strengthen into Wednesday. Gales and very steep hazardous seas south of Cape Sebastian beyond 5 nm from shore this morning. Conditions will deteriorate tonight through Wednesday, and have expanded the gale warning to areas beyond 3 nm from Cape Blanco southward. Although the strongest winds will be south of Port Orford, steep to very steep wind-driven seas are expected as far north as Cape Blanco. For simplicity sake, have expanded the Gale Warning for areas south of Cape Blanco beyond 3 NM from shore. Elsewhere, Small craft advisory conditions will continue through Wednesday.

The thermal trough is expected to move inland Thursday with a slight and brief improvement in conditions. Seas and northerly winds are likely to gradually increase late in the week as high pressure centered far offshore builds.

-Schaaf

FIRE WEATHER . Updated 130 PM PDT Monday, 13 July 2020 . A warming trend is expected through mid week with hot and dry weather developing across inland areas. High pressure will strengthen over the Eastern Pacific Ocean and nudge into the area. At the surface a thermal trough will strengthen along the coast. This pattern will bring northerly winds to inland areas with offshore northeast winds along the coastal areas and into western Siskiyou. Temperatures are expected to peak on Wednesday with highs 5 to 10 degrees above normal for inland locations.

The area will see a drying trend, especially with recoveries. Nighttime and morning northeasterly winds over the ridges/upper slopes from the Cascades west will trend stronger through Wednesday morning, winds strongest winds over the Kalmiopsis and western Siskiyou County. Gusts of 20 to 35 mph are expected over these ridges, especially in the overnight/morning hours. With the drying from offshore/northeast winds, expect overnight/morning recoveries to dip into the moderate to locally poor category, especially for ridges in Western Siskiyou County and the Coast Range.

Also of note for this week's weather, north to south oriented valleys located west of the Cascades, like the Illinois and Umpqua, will feature gusty afternoon/evening north winds as the thermal trough strengthens.

Heading into Thursday, a weak low to the south may result in some mid level moisture and instability developing into Modoc County with a slight chance for thunderstorms. Note, the best chance for storms is expected south of the area. Temperatures will remain hot on Thursday across the area, then trend a couple degrees cooler Friday into Saturday as an upper trough moves inland to the north, weakening the high pressure ridge and thermal trough pattern over the area. However, Sunday and early next week, the upper ridge may restrengthen with a surface thermal trough becoming positioned inland. This may bring increasingly hot and dry conditions to inland areas.
