This week will not be entirely cut and dry when it comes to precipitation types. The reason, the cold air that may be able to seep further south than what the models currently are showing. If this occurs, some days could feature a mix of rain and snow in the northern regions. I am not sold that it will be that way, but it MAY enter teh forecast. The NWS in Sterling has just added that possibility for Tuesday and Tuesday night in Maryland and Northern Virginia. Right now, expect cold rain and maybe that some sleet could be involved Tuesday in northern regions.
Unfortunately, a chance of rain or showers will persist all week after a rather balmy Monday (Highs in the 60s) a cold front stalls over the area and is a conveyor belt for precipitation in several waves as systems ride along the front.
Why might we see some frozen precipitation out of this? A cold hogh in Eastern Canada could be stronger than forecast or further south. If either of these are true, more chances for wintry weather could nter the picture. As of this morning, I am thinking that the synoptic set up just is not right.
We look drier next weekend after the last wave of precip moves through Friday Evening. Christmas week looks seasonal early with a chance that right around Christmas day or shortly after, colder air invades!
All for now!
