75 Degrees Monday! Mild Weather For The Week Ahead

April 7, 2014

We didn’t hit the record, but the high of 75 degrees in Portland today was the warmest since September 19th!


Quite an achievement considering we started with low clouds/fog in some areas this morning and no easterly wind surfacing in the metro area.  There was a light east wind in the Gorge the first half of the day with gusts around 30 mph in the Corbett area.  A big help was the warmer than expected 850mb temp; it was +11.8 degrees over Salem at 5pm.  That easily pushed us into the mid 70s.  In past cases, that same temperature with easterly flow has given us a high temp between 78-82 degrees in April, so it could be even warmer!  Take a look at the maximum temperature each of the last 9 years in the month of April here in Portland:


Last year we didn’t see 70s until later in the month, when we had a 4 day stretch.

Tomorrow will be a little cooler, but still very warm.  A weak cold front sweeps across the region tomorrow night, giving us a quick shot of rain.  I expect less than .20″ here in Portland.

Then we get weak ridging through this upcoming weekend.  The ECMWF had a chilly trough swinging by just to our east on Saturday, so it was cooler Friday and Saturday.  I ignored that since its ensemble members didn’t support that idea.  Either solution is dry, so it appears we have very little rain in the next 7 days.

Enjoy the mild and mainly dry weather the next few days!  Our 7 day forecast is real pleasant for early-mid April:

7 Day

Models show temperatures near or maybe a little above average in the next 10-15 days.  I sure don’t see a long cool/wet period;  more likely just typical warm, then cooler weather periods.  You can see this on the 850mb temp chart from the 12z ECMWF and the new 00z GFS:
