Clouds, showers, cooler temps as look towards week ahead

Clouds, showers, cooler temps as look towards week ahead

Another day of active weather across western Washington with showers at times and even a few sunbreaks.  Plan on breezy conditions as well associated with the showers. 

We are still getting some snow across the mountain passes this morning. At pass level the snow should turn to mostly rain by the afternoon. But we can't rule out a strong shower bringing that snow level back down to around 3000 feet temporarily. Highs in the lowlands will hit the upper 40s to low 50s.

Monday is looking cool as well, with showers at times. The large area of cool unstable air is going to take awhile to move through. 

Highs for the first half of the week are going to stay in the low 50s with morning lows in the upper 30s and low 40s. The shower chance lingers through Wednesday. 

The good news for sunshine fans comes mid-week as we also go partly sunny.

Clouds, showers, winds - More of the same expected through the week

Clouds, showers, winds - More of the same expected through the week

A cold front is approaching the coast as we speak.  Plan on showers for the morning hours, turning over to rain by the end of the day.  Rain will be heavy at times with gusty winds by late this afternoon and evening.  Highs this afternoon will hit the upper 50s to low 60s.

Monday we are behind the cold front so the rain will taper back to showers for the morning commute. You can still bet on plenty of showers during the day with highs in the upper 50s to low 60s.

Another batch of moisture rolls in Monday night and Tuesday morning. Be ready for more rain and wind. Some areas will feel gusts up to 45 mph by Tuesday morning. Highs will only climb to the mid-50s.

We have a chance of seeing a little sun on Wednesday and Thursday.

Right now the forecast models have a fairly weak system moving through on Friday bringing more showers.

Expect mild temps and more sunshine this week

Once again we have some spots waking up around freezing Sunday morning. More sunshine is on the way today with highs topping out in the upper 60s and low 70s.

High pressure is going to keep us dry for at least the next five days. Monday we will get a stronger push of marine air in the morning, but sunshine will burn that away rather quickly. Highs will hit the upper 60s.

Tuesday through Thursday are looking mostly sunny with highs dropping back to the mid-60s.

Right now our next best chance of getting some rain around here comes late Friday. But even if we get some showers out of this weak system they will be fairly light.  Highs will hit the upper 50s.

Mostly sunny with cooler temps for much of the week

There will be pockets of fog outside Sunday morning.  Most areas are waking up to sunshine and cool temps.  The rest of the day will be mostly sunny with highs in the upper 60s and low 70s.

High pressure will keep us dry again on Monday with filtered sunshine by the end of the day.  Highs will stay in the upper 60s and low 70s.

A weak system will brush by us from the north late Monday and early Tuesday.  The north Sound could see a few light showers.  Most of western Washington should stay dry.  By Tuesday afternoon we are back to partly sunny skies.

Right now the forecast models say high pressure will dominate the rest of the week.

First week of fall comes with clouds, light drizzle, and some sun

First week of fall comes with clouds, light drizzle, and some sun

It’s going to be a chilly start to Sunday with early morning lows hitting the 40s in the outlying areas, and 50s in downtown Seattle by dawn.

Morning clouds and spotty mist and drizzle will burn back by mid-day, revealing partly to mostly sunny skies.  Highs will head into the upper 60s to near 70 tomorrow.

Monday will be even a bit warmer, but increasing clouds Monday night into Tuesday morning may drop a bit of drizzle or light rain.  Otherwise, we'll hang on to the fairly quiet early fall pattern of 'a.m. clouds/p.m. clearing' through the middle of the work week.

By Friday, an approaching disturbance will throw some cloud cover in our direction by the afternoon.  We'll have a good shot at some rain Friday night into Saturday morning.  It doesn't look like a real soaker--not yet a drought buster--but if it does materialize, it will be the most significant rain we've had for awhile.  And we sure could use it!

Have a great day,
Shannon

Sunny skies, warm temps sticking around for the week

Dry streak may end soon, but sun not done in September

Dry streak may end soon, but sun not done in September

A season-changing frontal system is at our doorstep...it already feels like we're wrapping up summer and heading straight into fall this morning.  The skies lit up with thunder and lightning last night over the Cascade crest, but Sea Tac managed to hold on to a dry rain gauge...we've now gone 48 straight days without rain at the airport, and if we manage to get through today without measurable precipitation, we'll get to 49.  However, the count will almost certainly end there, and we'll have to settle for 2nd place in the 'driest ever on record' rankings...the old record was 51 days in the summer of 1951.

The clouds really filled in already overnight, and the wind picked up, too...the treetops were swinging around for the first time in a long time as the wind whistled through them this morning.  Some early drizzle and light rain is already falling near the coastline, and the interior may see a few scattered showers today, too. However, the bulk of the rainfall should wait to fall until very late tonight and early Monday morning.  Therefore, we'll spend most of the day clouding up and cooling down.  Highs will top out only in the middle 60s today for Seattle, Tacoma and Everett.

With rain hitting the pavement overnight, look for VERY slippery morning commuting on Monday.  The oils and dirt that have accumulated on the roads during this long dry spell will mix with the rain and create a very slick scenario.  Leave extra room between you and the car in front of you as you drive to work or school tomorrow morning.
