Yes, it's May -- but some people in parts of Maryland and Virginia needed their coats and ice scrapers Tuesday morning.
Don't worry too much, though -- it won't be that cold for the rest of the week.
Storm Team4 Meteorologist Sheena Parveen said afternoon temperatures will be cool for the remainder of the week, with highs in the low to mid 60s.
Morning temperatures will be in the mid 50s.
Storm Team4 is also tracking what could be a nor'easter during Mother's Day weekend. Heavy rain is expected between Friday night and Saturday.
Parveen said the incoming storm is technically a nor'easter because of the wind patterns. It may be windy Sunday as the storm moves out of the area, but Sunday will see a high of 70 degrees.
The National Weather Service issued a freeze warning and a frost advisory for early Tuesday morning for parts of Maryland and Virginia north, west and southwest of the District.
Monday night was the coldest it will be all week, with temperatures in the mid to upper 30s in those areas of Maryland and Virginia. D.C.'s temperatures hovered in the low to mid 40s overnight and into Tuesday morning.
Even though this is unusual for our area this time of the year, D.C.'s Monday night low was nowhere near the record, which was 34 degrees back in 1947.
