Outlook:
The weather today remained a little on the brisk side with high temperatures ranging from the mid 50s to the lower 60s.
Tomorrow, temperatures will surpass what they hit today -as they climb into the mid 60s. As surface temperatures warm into the lower 50s, winds will once again increase out of the south/southwest at 10-20 mph under mainly sunny conditions.
Clouds begin to thicken Sunday evening as a weakening cold front makes an approach on the region. Most of the dynamics associated with this system will remain well north of the region, keeping the chance of precipitation to a minimum Sunday night/Monday morning.
Say Hello to Old Man Winter. . . well sort of:
Late Monday night, a very intense low pressure system will begin to develop in the upper Midwest (known as cyclogenesis). As the low deepens, a warm front will approach the region from the south very late Monday night/Tuesday Morning. As this ocurrs, lifting associated with the developing frontal structure will allow showers to develop/expand across the Mid Atlantic.
By Wednesday morning, the strongest cold front of the Fall season is knocking at the region's western doorstep, and clears the District by Wednesday afternoon/evening. (Note...timing differences exists between various weather models that have yet to be worked out).
After the front passes, surface temperatures fall off quickly into the low-mid 30s out west (possibly lower) Wednesday night. Based on their latest discussion, the weather service seems a bit concerned about Precip-type after the front passes, especially on the western flank of the Appalachians as temperatures plummet into the range favorable for snow-growth processes. At this point, surface temperatures in the immediate metro region do not look to favor any type of rain/snow mix post frontal passage.

Temperatures Thursday fall into the lower 50s, and possibly fall into the upper 40s by Friday/Saturday of next week.
Weather Underground develops new Satellite viewer:
After unveiling their new NEXRAD products with rain/snow line capabilities last month, Weather Underground has developed another great analitical tool-an improved satellite/radar viewer for the United States (click here). The interface allows viewers to pan, zoom, loop, and overlay various fields onto the satellite image.

I thought this was pretty neat.
