Strongest cold front of the season slated to move through the region tomorrow afternoon with some scattered showers (maybe a thunderstorm). Behind the front expect much cooler temperatures as a strong Canadian High moves over the Mid Atlantic. Low temperatures Friday morning will likely dip into the low-mid 40s north of DC and into the mid-upper 40s to near 50 south. Folks out in the higher elevations of the Appalachian may see temps dip into the 30s.

Saturday looks perfect with highs near 70, light winds, and little cloud cover. However, the pattern we're in at this time forces the cool high's east fairly quickly, so we begin another warming trend Sunday as the high pressure moves east.

The tropical low in the Caribbean has been trying to get organized over the past 24 hours, and has recently shown an increase in thunderstorm activity around its center of circulation. Upper level conditions are become more conducive for development...and I still expect this system to become our next tropical depression as it drifts northwestward.
