Freeze Warning for parts of the D.C. area through 10 am Friday

UPDATE 10pm: The *Freeze Warning* has been expanded to include the entire abc7 and News Channel 8 viewing area.{ } That said, we are not expecting everybody to dip down to freezing.{ } For example, it's unlikely that the city center of Washington and immediately along the waterways will drop to freezing. Here is the updated map:

Freeze Warning Midnight through 10am Friday

{ }

A Freeze Warning has been issued for parts of the D.C. area including everywhere along I-95 and points west. This does not include the District of Columbia. Below is a look at the warning shaded in light blue. Warnings along and east of the Blue Ridge start at 3am Friday and continue through 10am.

Freeze Warning Midnight through 10am Friday

Temperatures will fall into the 30s throughout the region and possibly even upper 20s in the extreme western suburbs and higher elevations. It may also fall into the upper 20s in the Blue Ridge Mountains.

Per the Sterling NWS Office,

"A Freeze Warning is issued when significant, widespread freezing temperatures are expected.

A Freeze Warning is issued in the autumn until the end of the growing season (marked by the occurrence of first widespread freeze). The normal end of the growing season is mid to late October west of the Blue Ridge and early November east of the Blue Ridge. However, during anomalously warm autumns, the growing season may be extended past the normal end of the growing season."

4km NAM Model forecast for tomorrow morning

Above is a look at the forecast lows tonight from the 4km NAM model through Now again, these are forecast lows, so they may not be quite as cold as above if the wind stays up by a few mph or if a few pockets of clouds hang around. Regardless, it will be cold and many spots will experience a hard freeze.

Areas around and east of D.C. shouldn't see quite as cold temperatures because of elevation (closer to sea level) and the main influence from the proximity of the Potomac River and Chesapeake Bay (Water temperatures are still 60°F in both bodies of water).

High temperatures should reach the mid 50s Friday and again dip into the 30s Saturday morning. Additional Freeze Warnings may be possible if areas don't have a hard freeze tonight. If this is the case, we'll let you know. Warmer temperatures in the upper 50s to around 60 degrees are expected through the weekend.
