Monday Evening Update: December 16 2019

The Winter Weather Advisory has been expanded back into part so of central Maryland. If you read my prior report, this fit with the same area I suggested could get icing in northern Harford, Baltimore, and Carroll Counties.

The irony is that where there was less snow farther north this morning, will be the more likely areas to get icy this evening. Below are updated conditions as of 5 PM.

The added counties of northern Harford, Baltimore, Carroll- through midnight. Ice mainly on sidewalks and elevated surfaces. Total accumulation up to 0.10 inch ice.

Temperatures at 5 PM

Here is the latest look at temperatures and the radar simulation. Freezing rain is fickle and can lead to icing in patchy areas between some regional weather stations that might show slightly warmer temps.

• These reports are form the regional weather stations.
• It is possible have colder pockets in between as just one or two degrees can make the difference for ice.

Winds are from the colder Northeast which will hold the cold through the evening.

Signs To Look For Develop Ice

• Touch the door on your car, or a car that has been parked for a few hours. The metal will freeze first. Then check the windows. If these feel like droplets are freezing, then next could be the pavement.
• Check metal rails or your mailbox for icing.
• Car Thermometers are not totally accurate, but when it is wet outside it displays more realistic numbers. You should be driving for a few minutes to make sure the heat from your engine is not falsely warming the display number.
• Caution: When ice is ‘patchy’ the places that are more likely to freeze are

In the shade:

• North side of hills or buildings
• Elevated surfaces like ramps or bridges
• Concrete sidewalks before dark road pavement
