wrapping up feb... (pm.28.feb.12)>

Skies are partly cloudy as we approach sunset this evening, after a day which featured some nice sunshine, but also periods of clouds, and a round of thundershowers with some sleet and small hail this morning between about 10:00 and 10:40am.  I measured 0.10" (3mm) of rain, along with a high temp of 59.5F (15.3C) which occurred early this afternoon during an extended sunny break.

The concern about a "brief, passing shower" that we've had in the forecast the last couple of days finally came to fruition this morning... but I think we got a little more than we bargained for.  Although it was short-lived, there were rumbles of thunder and even some ice pellets; evidence of a pool of very cold air in the upper atmosphere associated with our weak upper-level disturbance.  If you got caught out in it, I'm sure it wasn't very pleasant.

That disturbance is now moving east-southeast of us, and will be gradually replaced by a weak ridge of high pressure as we move into the middle and latter parts of the week.  It's doubtful that we'll see 100% sunshine, but it should be generally bright and pleasant nonetheless, with temperatures warming up a bit more by Saturday.  There is still an indication of a new system moving in by Sunday, which will increase rain chances once again...
