Sunny and dry conditions today in southwestern Connecticut, combined with gusty winds, pose a fire threat to the region.

The National Weather Service, in issuing a "red flag" warning from 10 a.m. to 6 p.m., says that winds of 15 to 18 mph, gusting as high as 30 mph, could rapidly spread any fire that ignites today because of very low humidity and dry ground conditions.

The daytime high temperature, meanwhile, is expected to rise to about 50 degrees and skies will be sunny.

Tonight should be partly cloudy, with the temperature falling to a low in the mid-30s and the winds calming to between 4 and 7 mph, the NWS says.

Tomorrow, there is a chance of showers, mainly after 11 a.m. Skies will be mostly cloudy, with a high temperature near 55 degrees and a south wind between 7 and 14 mph. There remains a slight chance of showers tomorrow night and the low temperature is expected to be in the mid-40s.

Thursday is likely to be mostly cloudy, with a high temperature in the mid-50s. Clouds are in the forecast for Thursday night and the low temperature will be about 40 degrees.

The outlook for Friday, according to the weather service, is sunny and temperatures rising to the mid-50s.
