SYNOPSIS. Showers will decrease through tonight as a cool weather system departs east of the area. A front will approach the coast Wednesday and move inland on Thursday. A warming trend is expected by the weekend as dry weather is likely through next Tuesday.

SHORT TERM. TONIGHT THROUGH FRIDAY . Satellite and radar showing showers continue to move onshore. There is enough instability for at least a chance of thunderstorms through early this evening. NBM thunder probability is about 20-30%, mainly from the coast range into the Cascades in the north Willamette Valley into SW Washington. Wind sheer is modest so expect to see stronger cells develop brief heavy rain. Developing sunbreaks will help energize storm development, At 2 pm a couple of lightning strikes were detected in the Woodland WA area so will have to watch closely over the next

Showers will decrease this evening and be mainly confined to the mountainous terrain before ending. Chances for thunderstorms will also end in the evening. But next up is a warm front now developing between 130-135W off the WA coast. This will bring rain mainly to the NW part of the CWA. Models indicating areas south and east of about Salem will not get much pcpn, if at all. Heaviest rain will be over the south WA coast and Willapa Hills with 1/2" to 1" Wed/Wed night. The cold front moves into the area early Thu morning then east of the Cascades in the afternoon. Models have been trending the pcpn further north over the past several runs and have adjusted the forecast to follow this trend. It will be fairly breezy at the coast with the warm front tomorrow with gusts 25 to 35 mph for the north OR and south WA coasts and compares favorably with most of the ECMWF ensemble members.

Snow levels today are expected around 5,500 feet but will be climbing to about 8000 feet by Wed afternoon as the warm front pushes closer to the region. Then dips closer to 5000-7000 feet Thu night behind the cold front, but by then pcpn will be tapering off. Temperatures will trend toward seasonal normals Wed through Fri with inland highs around 70.

LONG TERM. FRIDAY NIGHT THROUGH MONDAY . Building high pressure is expected to bring drier weather to the area through the weekend. Models are in decent agreement that an upper level ridge will shift over the region by Saturday and build through Sunday as a deep upper low sets up in the Gulf of Alaska. But later Sunday into Monday the upper trough sags toward the PacNW, but it appears to remain dry for our area. Temperatures are expected to warm into the 70s over the weekend. Monday should see similar conditions. NBM guidance suggests PDX has 20 to 30% chance of reaching 80F both Sunday and Monday. Overall, the start of October should be dry, relatively warm, and a good weekend to get outside. /mh /DH

AVIATION. Scattered rain showers with a few isolated rumbles of thunder will continue across northwest Oregon and southwest Washington, ending from west to east over the next several hours. Between showers, inland terminals should remain under broken VFR ceilings. Some models even suggest that clouds will scatter out once the showers come to an end later this evening. Along the coast, some sea haze/mist may affect visibilities at KAST and KONP (where it has been observed the past few hours) in the southwest/onshore flow pattern this evening through the night.

Stratus should begin to spill back into the area overnight, first along the northwest Oregon and southwest Washington coasts. Thereafter, it should migrate into the northern Willamette Valley, while the southern end of the Valley could stay comparatively cloud-free. These clouds should reduce ceilings into the MVFR category inland and MVFR to IFR categories along the coast. Furthermore, depending on the arrival time of these low clouds, some fog may be allowed to develop in clearing across the Willamette Valley overnight. This could have a significant impact on visibilities, with the potential for a drop into the IFR category, but uncertainty is very high at this time.

KPDX AND APPROACHES . Conditions between showers should remain VFR, while any heavy showers/thundershowers this evening could result in both visibility and ceiling drops into the MVFR (or briefly IFR) category. Models suggest clouds will break up into the scattered category later this evening, which may promote fog development overnight, though uncertainty in this scenario is high at this time. By morning, some additional clouds should spill in to the area from the northwest. -Bumgardner

MARINE. Recent observations indicate seas remain high at around 15 feet at 13 seconds over the waters, but these are expected to be trending down throughout the evening and overnight Tuesday night. By Wednesday morning, seas are expected to drop into the 8 to 10 foot range, but winds will be increasing out of the south. Small Craft Advisories have been issued to cover the potential for sustained winds of 15 to 25 knots, with gusts at times surpassing 30 knots in the northern waters. The strongest winds are expected late Wednesday morning through Wednesday evening, but gusts over 20 knots could continue through sunrise Thursday morning. Expect southerly wind waves up to 8 feet atop a 7 to 10 foot westerly swell in the northern waters during this time.

Winds turn northerly behind a cold front Thursday evening. Between an area of low pressure stretching north from California and a high pressure system over the eastern Pacific, these northerly winds could gust to 25 knots on Friday. -Bumgardner
