Warmer days ahead, but keeping an eye on the weekend
After a chilly start Wednesday Morning, expect a nice warming trend through the end of the week. By the weekend, we will be closely watching the timing of an approaching front that could bring rain and storms.
It really hasn't felt like April lately, but that will change for a few days. A nippy start again Wednesday with temperatures in the mid/upper 30s early. This could lead to some patchy frost, especially north and east of the city. Plenty of sunshine the rest of the day with afternoon highs in the mid/upper 60s (low 60s mountains). Not as cold Wednesday Night with lows mainly in the 40s, a few upper 30s north. Thursday should be even warmer with sunshine and afternoon highs in the mid/upper 70s (low 70s mountains). By Friday, a southerly flow increases which could help boost temperatures to the upper 70s to near 80 under a sunny to partly sunny sky. It should remain dry right through Friday Evening to start the weekend.
WEEKEND WEATHER MAKER
A system that is currently (late Tuesday) approaching the US northwest coast should push a cold front our way by Saturday. There remains some timing issues between both the GFS and European Model. As you can see on the maps above, the GFS Model brings the showers in locally as early as Saturday Midday. But, the European Model favors a slower moving front keeping us dry locally through sunset Saturday and the better rain and storm chance Saturday Night and into Sunday. So, there is the chance that you could possibly be able to do some outdoor activities Saturday IF the front is slower to arrive as the European Model shows. We'll keep you updated on the timing of this system.
Aside from the timing differences, there are also some rainfall projection differences. The GFS Model has the rain and storms starting earlier and lasting longer. The GFS Model projects over 3" of rain through Sunday Afternoon. Meanwhile, the later arrival noted by the European Model has a shorter duration of rain and storms keeping the rainfall projection at just over 1". Either way, a soaking possible!
As far as severe weather, we will have to watch the leading edge of a potential line of storms that could develop Saturday Night. Right now it is still too early to determine the overall threat level. But, for now, be weather aware as some storms could at the very least produce some damaging wind gusts and heavy downpours.
As mentioned in our previous post, another big cool down could occur starting Sunday Afternoon. As the rain moves out and the northerly flow returns, Sunday Afternoon temperatures could remain in the 50s. The coolest day could be Monday with afternoon highs possibly staying in the low 50s (40s mountains). By next Monday Night, local temperatures could again dip into the 30s. So, the risk of frost is again possible, A warming trend should follow for the remainder of the week.
