First Thunder Day

March 28, 2006

As I mentioned on the 10 & 11pm broadcasts tonight, March 28th will definitely go down as the first widespread "thunderstorm" day in the spring here in the Northwest.  We recorded over 200 strikes across Oregon.  They were spread all across the state from the Coast to the Idaho border.  Scattered storms developed and moved north, away from a California system supplying the moisture.

Tomorrow the flow overhead turns onshore, which should give us lighter afternoon showers.  Onshore flow also means a bit more cloud cover and cooler temperatures.

Long range maps show this active pattern will continue with deep troughs dropping in towards California, which gives us southerly flow and moisture, then cooler air as they move on through.  Those of you looking for 70 degree weather will have to wait into the first week of April at least….Mark

Thunderstorms Developing…2pm

March 28, 2006

Looks like temps warmed plenty for convection to pop up in the "perfect pattern" for thunderstorms (see last night’s blog).  Several lightning strikes already at 2pm near Mill City and Sweet Home.  Unfortunately, the PDX-RTX radar is out of comission for at least 2 more days!  These showers will move either due north or slightly north-northwest, which puts them over the metro area by commute time.  Could get interesting for a few hours…Here is a link to "another" radar in this time of weather geek desperation.  Of course it’s not nearly as powerful as the other WSR-88D radars, but it’s better than nothing right?  Mark
