A well-defined cold front passed through the area early this morning sending the temperature and humidity into a deep plunge. Today's high was 69 degrees just before the front arrived. If the sun comes out this afternoon it may temporarily reverse the temperature drop, but it will be close to the mid 40s by the time midnight rolls around.

Clear, dry, skies will allow the temperature to drop into the lower 40s in the city by tomorrow morning, making it the coldest we've seen since early April. Get away from the immediate coast and there is a good chance for below freezing temperatures overnight. Tuesday's high will struggle to reach 60 as a big high pressure system remains to our west.

That big high pressure system is going to slide eastward as the week progresses and that, as you might have guessed, will lead to a big warm up. Wednesday through Friday will see highs near 70 under sunny skies. Next weekend is looking a little warmer still, with highs in the lower to mid 70s on both Saturday and Sunday. There is almost no chance of rain for at least another week.
