Thursday forecast: Cloudy with highs near 40

Cloudy skies and temperatures in the 30s are in the forecast Thursday in Baltimore as high pressure moves off the coast and two low pressure systems move toward the region, according to the National Weather Service.

A narrow range of temperatures is expected, with morning lows in the mid-30s and afternoon highs in the upper 30s to around 40 degrees. A 10 mph breeze is expected to make temperatures feel about 5 degrees colder.

Two low-pressure systems are expected to approach the mid-Atlantic on Thursday night, one from the Ohio Valley and another from the Gulf Coast, but while they are looking to produce a major snowstorm for New England, only a wintry mix turning to rain is forecast for Baltimore.

An inch or less of snow accumulation is expected across Central Maryland, with something like a hundredth of an inch of ice possible in parts of northern Carroll, Baltimore and Harford counties, according to weather service forecast maps.

The region is expected to stay in between the two approaching systems, avoiding any major snowfall, according to weather service forecast discussion:

OUR AREA WILL REMAIN IN BETWEEN THESE TWO SYSTEMS...KEEPING ANY HEAVY PRECIPITATION AWAY FROM OUR AREA. HOWEVER...WARM AND MOIST AIR WILL OVERRUN SURFACE COLD AIR IN PLACE...LIKELY CAUSING LIGHT PRECIPITATION ACROSS THE AREA TONIGHT. THERE WILL BE ENOUGH COLD AIR NEAR THE SURFACE FOR A LIGHT WINTRY MIX...MAINLY FOR LOCATIONS NEAR THE MASON-DIXON LINE AND ALSO ALONG/WEST OF THE BLUE RIDGE MOUNTAINS.

Weather service precipitation forecasters have meanwhile increased Central Maryland's odds of at least an inch of snow, to 30-50 percent, from about 10-20 percent a day ago.

Overnight lows Thursday into Friday are expected in the mid-30s, with highs Friday nearing 50 degrees.

High pressure is forecast to return for the weekend, with clear skies and highs in the 40s. A chance for rain returns Monday.
