This spring's weather roller-coaster continues rollicking the region, with the National Weather Service issuing a "freeze warning" for tonight and early tomorrow -- a stark contrast from the 80-plus-degree temperatures several weeks ago.

Skies today will be sunny and the daytime high temperature in southwestern Connecticut should rise to the mid-50s, with a northwest wind between 14 and 23 mph.

But tonight, under clear skies, the temperature is expected to drop to the low-30s -- at or below the 32-degree freezing mark. There will be a northwest wind 18 to 21 mph, later decreasing to between 9 and 12 mph.

Tomorrow should also be sunny, with a high temperature in the upper-50s, but there is a slight chance of showers after 2 p.m. Nighttime also brings a chance of showers, mainly after 8 p.m. as skies could over and the temperature drops to a low in the upper-30s, the NWS says.

Sunday promises to be sunny, with a high temperature near 60 degrees. The overnight low should be about 40 degrees.

The outlook for Monday, the weather service says, is sunny and temperatures rising to about 60 degrees.
