a showery spell... (pm.15.apr.15)>

Wednesday's stats:

Low temp: 56.5F (13.6C)
High temp: 67.1F (19.5C)
Rainfall: 0.11" (3mm) -- as of 9:30pm

There are occasional light rain showers in the area this evening, with mostly cloudy skies. It's been a day of extreme variability, with almost full sunshine for a few hours this morning, followed by rapidly increasing clouds before noon, and then several periods of light rain showers and thunder -- the first of which got started around 12:45pm.  Rainfall amounts have been light, with a few glimpses of sunshine occurring in between.  Temperatures today have been several degrees cooler than normal, but not really all that unpleasant.

The showers today are not a surprise... as we've been anticipating this since late last week.  There's a batch of unseasonably moist air lurking just to our south, with just enough battle between temperature disparities in different layers of the atmosphere to provide the 'lift' necessary to squeeze out these rain showers.  Conditions will remain favorable for a few more periods of showers/thunder through Thursday, though we'll probably continue to see some back-and-forth between sun and clouds as well.

Significantly drier air is showing up on the computer models -- sweeping in by late Thursday night, and sticking around through most of the weekend.  That drier air will be accompanied by a decent warm-up as well, which will put us right back in the normal range for mid-April.  An upper-level disturbance will come knocking by late Sunday night or Monday, but very limited moisture may restrict the rain potential.  All in all, the extended forecast contains nothing wildly out of the ordinary for this time of the year.
