SYNOPSIS
A ridge of high pressure will remain overhead today, bringing another day of unseasonably warm temperatures to the area. Inland valley temperatures are expected to reach the upper 80s to low 90s today. Saturday night into Sunday, winds throughout will shift to onshore flow as a shortwave trough moves over the region, bringing cool yet still above seasonal normal temperatures into early next week.

SHORT TERM
Now through Monday... The positively tilted ridge axis remains directly overhead but will slip southward through the day as a trough moves eastward across the northeast Pacific. The thermal trough has shifted inland toward the Willamette Valley and will continue towards the Cascades this afternoon. This has allowed the surface high to shift winds along the coast from offshore to onshore. Hi-res models have stratus developing along the coast this morning and observation sites near Tillamook support this development. This will moderate temperatures this afternoon. Temperatures along the coast will be 8-10 degrees cooler than yesterday, peaking in the upper 60s to low 70s. The Willamette Valley will see another toasty day in the mid to upper 80s. Chances are high (70-90%)
that temps peak at or above 85 degrees but are much lower than Friday to reach 90, peaking at 20-40% only around the Portland/Vancouver metro. Widespread cooling is expected Sunday as the upper- level shortwave trough moves towards the coast, weakening the ridge overhead and pushing it eastward. Sunday highs peak around 60 along the coast an in the upper 70s to near 80 in the interior valleys. Monday will see the shortwave come onshore across the PNW which will drop temperatures even further as northerly onshore flow increases. Highs along the coast will remain near 60 while interior valleys only peak near 70.

With such unseasonably warm temperatures for early Spring and coming out of cold weather, there is no doubt people will visit rivers, lakes, and the ocean for SW Washington and NW Oregon this weekend. It is important to remember that rivers and lakes remain dangerously cold with water temperatures mainly in the 40s. Such temperatures can easily cause cold water shock for those without proper cold water gear, resulting in an involuntary gasp of air that can lead to drowning. Be sure to bring a life vest and be extremely cautious around rivers, especially with snowmelt causing cold and swift currents! -Batz/JH

LONG TERM
Tuesday through Friday...WPC cluster analysis has moved more towards a solution favoring ridging re-developing by the middle of next week. Nearly all ensemble members display relatively strong and broad ridging by Wednesday next week, allowing temperatures to climb to the upper 70s in the latter half of the week. Agreement lessens into Friday as there is a 10-20% chance of a trough developing and pushing south into the region. This trough would bring more seasonable temperatures and light rain showers back to the area, but there is still not enough model convergence to be certain. Cluster analysis trends farther toward a trough developing into early next weekend.

AVIATION
High pressure and dry northerly flow aloft will maintain VFR across region today into tonight. Thermal trough will gradually move across the region, from over the Coast Range this am to the Cascades by early evening. As such, will see uptick of north to northwest winds this afternoon.

Again, most areas remain VFR under mostly clear skies today.
Exception will be for pockets of low clouds along the coast this am, mainly in the larger, wind-shelter bays/valleys such as Tillamook area. As onshore flow increases today, will see areas of marine IFR/lower end MVFR stratus reform along the coast this afternoon into the evening, then spreading into the Coast Range valleys tonight. Areas of MVFR stratus likely against the lower slopes of the Cascades foothills late tonight into Sunday am.

PDX AND APPROACHES...VFR today as high pressure maintains mostly clear skies. Will see uptick of northwest winds later today into this evening as onshore flow picks up a tad. Should see areas of MVFR stratus form to north and east of KPDX late tonight into Sunday am as marine layer deepens. /Rockey

MARINE
High pressure still anchored well offshore. Thermal trough is just inland, and will continue moving farther inland today. Will maintain north to northwest winds on the water today into tonight. Gradients tighten just a tad, enough such to get winds gusting 20 to 25 kt at times this afternoon into this evening. As such, have put up Small Craft Advisory for that time.
Seas mostly 5 to 7 ft.

Little change for Sunday into early next week, as high pressure remains anchored well offshore, and lower pressure well inland. As such, will maintain north to northwest winds on the coastal waters. Could see gusts 20 to 25 kt at times in afternoons and evenings. Seas remain mostly at 5 to 7 ft.

PQR WATCHES/WARNINGS/ADVISORIES

OR...None.
WA...None.
PZ...Small Craft Advisory from 3 PM this afternoon to 1 AM PDT Sunday for PZZ251>253-271>273.
