Last Post For June

June 22, 2007

SnapshotHere’s a slightly updated version of the graphic I used earlier in the week.  Remember the warmest June day (101) ever was followed the next by a 102?  What a difference for this weekend.  A cold upper-level trough moves inland by Sunday.  We should avoid the showers again tomorrow, especially since the clouds offshore are broken-scattered again this evening.  Then a cool and wet day Sunday.  Low lifted index (near zero) and some decent CAPE definitely point to thunderstorms Sunday.  Not a huge outbreak, but a cool spring-type pattern.   Brrr…
Models agree quite well on next week’s pattern.   Very similar to this week.  We get brief ridging Monday-Wednesday then ANOTHER cold trough approaches the latter half of the week.  Once again, as I mentioned last night, we may get more of a southerly upper-level flow as the low approaches.  That’s compared to the last two troughs and their west-southwest flow.  A setup like this is better for thunderstorms in our region.  Definitely good for thunder east of the Cascades late week.
I’m off on vacation for the next week and a half.  Well, at least after 9am on Sunday I will be.  I’m filling in tomorrow night and again Sunday morning on GDO.  Then I won’t be back until the 4th of July.  Enjoy the rest of the month…Mark
