This morning's sunshine was the end of the sunny, springlike weather for today. The showers and clouds that are moving across the region now mark the cold front that will usher in cooler, more March-like weather and, by tomorrow, a return to sunny skies. Here's the regional radar loop.

Forecasters out at Sterling say we have already seen the day's highs. We made it to 56 degrees here at The Sun, but the mercury has already turned downward as the sun vanished and clouds moved in. And the barometer as curved upward again. We'll slide into the 40s this afternoon and the wind will turn and become northerly as the colder air moves in. Showers won't amount to nearly enough - less than a tenth of an inch.

But it will be all uphill from here. Tomorrow, the first day of the northern spring, will be the coldest day of the next seven, with a high only in the upper 40s, well below the seasonal norms. The overnight lows this weekend will drop into the upper 20s to near freezing. But the sun will be back and stick around right through Wednesday of next week. Temperatures will rise gradually into the mid-50s this weekend to the low 60s by mid-week.
