| episode_narrative | A very protracted precipitation event affected the Delmarva Peninsula on the 14th and 15th. The region escaped the worst conditions as enough warm air came in before the heavy rain arrived. Nevertheless about a quarter inch of ice accrued on power lines and limbs in extreme northern Cecil County. Less ice fell farther south.A cold front moved through the peninsula the evening of the 13th. Extremely cold air moved south behind it. Unlike the usual pattern with cold frontal passages, precipitation occurred behind the front and slowly worked its way south during the early morning of the 14th. A weak low pressure system developed on the cold front in the Tennessee Valley on the 14th, but weakened as it moved east off the Delmarva Peninsula during the evening of the 14th. A very strong high pressure system built into northern New England on the 14th. The high moved offshore the evening of the 14th and the flow across the Middle Atlantic States became more easterly. This permitted warmer air to move back quicker into the region during the late afternoon and evening of the 14th just as a second and stronger low pressure system was getting organized over the Tennessee Valley. A secondary low formed near Norfolk during the early morning of the 15th and this not only accelerated the increase of warmer air, but also produced some heavy rain across the peninsula.A mixture of sleet, snow and freezing rain fell across Cecil County from around midnight on the 14th through the evening of the 14th. Freezing rain prevailed the rest of that night until air temperatures climbed above freezing during the early morning of the 15th. A shorter version of this scenario occurred farther south across the Maryland Eastern Shore. Only a couple of hours light freezing rain occurred across Talbot and Caroline Counties the morning of the 14th before air temperatures went back above freezing. Heavy rain moved across the region during the morning of the 15th. Storm total amounts averaged between 1.0 and 2.0 inches for the event, most of which fell during the morning of the 15th. There was some poor drainage flooding, but no serious problems were reported. The storm total in Federalsburg was 2.1 inches. |
