Scattered Thunderstorms are expected in the area once again this afternoon and evening. They will be similar to yesterday’s storms that produce frequent cloud to ground lightning strikes due to the massively unstable atmosphere.
The National Weather Service has issued a Severe Thunderstorm Watch for Southern Washington! This watch does not include Burien or the Seattle Metro areas, but these storms could push outflows (bursts of air from dying or dead storms) toward our area to spark more storms in the area.
Keep updated, and because of the danger of cloud to ground lightning strikes, if you see flashes above you or hear thunder, head indoors.
Temperatures reached the mid 90s in the Western Washington lowlands on Monday while an upper level low pressure system surged into the Northwest region bringing colder upper levels and swaths of mid level moisture. These ingredients came together to produce strong, frequent lightning producing thunderstorms that tracked across the Lowlands and the Cascades.
Rain showers are expected to continue throughout this morning and storms will start becoming more likely by around 3PM this afternoon.
With the Northwest summer giving us plentiful heat and sunshine, we’ve been lacking interesting weather content to feature and talk about on PSWxG. However, things are about to get interesting as a few changes occur during the next few days.
Yet another upper level system sweeps down from the Gulf of Alaska.
The system will move towards the Northwest in conjunction with a surge of searing heat in the low 90s in the lowlands and in the 100s further east on Monday afternoon. The brutal surface heat, combined with the cold upper level low and the waves of upper air moisture associated with the system will create an atmospheric recipe for wide spread thunderstorms on Tuesday and Wednesday. I will be publishing more up to date articles as the forecasts become more certain with audio or video updates. Stay tuned!
Unfortunately the storms, heat and wind increases are bad news to wild-land fire crews across the NW battling wildfires. The expected sporadic lightning in the Cascade mountains will likely spark new fires and the unpredictable pop-up storms will make fighting the fires very difficult. Hopefully some of the downpours have an effect on new and existing fires.
On another note; as I’ve done for the last six years, I will be traveling to Phoenix Arizona to storm chase and photograph the Southwest Monsoon Season for two weeks. I will be able to maintain the live stream and basic info about the weather on PsWxG but full articles may be sparse. I will also post photos and storm chase updates from Arizona.
I awoke early this morning to see giant rain droplets (probably hail that had melted on the way down) falling from brightly colored tall bubbling cumulonimbus clouds. I wish I had my live stream cam on record! Continue reading
The Puget Sound Region has been blessed with a streak of sunny hot days making us remember why we love summer in the Northwest so much. Alas, a return to reality is in order as rain and cooler temperatures are forecast for this weekend. Continue reading
One of the biggest weather trends for the past couple months has been the occurrence and effects of upper level low pressure systems. These tough to forecast systems bring a mixture of sun, rain, storms to the lowlands and even late spring snow to the higher mountains. Continue reading
