*The National Weather Service has issued a Winter Storm Warning for today*

Today: Windy and very cold with snow this morning, then clearing late. Temperatures falling into the upper 10s. Winds gusting over 20 miles per hour at times. Total snow accumulation up to 5 inches.

Tonight: Clear and unseasonably cold with a low around 5. Winds diminishing to near calm.

Tuesday: Sunny but cold with a high in the mid 20s to near 30.

Tuesday Night: Clear and cold with a low around 15.

The extended forecast calls for sunshine on Wednesday with a high in the mid 30s. Clouds and sun on Thursday with a low in the mid 20s and a high near 40. A chance of rain or snow showers on Friday with a low in the upper 20s and a high near 40. A chance of rain showers on Saturday with a low around 30 and a high near 40. Mostly sunny on Sunday with a low around 35 and a high near 50.

A Winter Storm Warning remains in effect for the Annapolis area and includes Baltimore and Washington. The snowfall has been lighter than expected across the region today; consequently, total snowfall amounts may only reach up to 5". This is due to the frigid air pushing into the system from the north and driving the moisture to the south. In addition to the falling snow, temperatures have plummeted from the upper 30s around midnight to the upper 10s at 9 a.m. Winds gusting over 20 miles per hour at times are creating wind chill values around zero. The snow should taper to flurries by noon, and the sun is expected to come out this afternoon. However, the mercury will continue to drop through the teens. Under a clear sky tonight, and with near-calm winds, thermometer readings will fall to near record-breaking levels with low temperatures on Wednesday morning between 0 and 10 degrees! After a frigid start to the day, Wednesday will be sunny but cold with highs in the upper 20s (the average high for this time of year is around 50). Temperatures will moderate later in the week with a system bringing another round of wintery precipitation to the region in the form of mixed rain and snow showers. By this weekend, temperatures will inch closer to seasonal averages for early March.

On the Maryland portion of Chesapeake Bay, a Small Craft Advisory is in effect through Monday night. Winds on Monday will come out of the north at 10 to 20 knots with gusts over 25 knots and waves from 1 to 3 feet. Visibility will be reduced in snow and fog. Winds on Monday night will come out of the north at 10 to 15 knots with gusts over 20 knots and waves from 1 to 3 feet. Winds on Tuesday will come out of the north at 10 knots with waves from 1 to 2 feet. Marine information is provided as general guidance. Boaters should always stay tuned to the latest forecasts and advisories from the National Weather Service.

The average high temperature for March 3 is 49 degrees and the average low is 30 degrees. The records at Baltimore on this date are 78 degrees in 1923, and 10 degrees in 2009. Today's sunrise will occur at 6:36 and the sunset will occur at 6:01. Weather data courtesy of the National Weather Service.
