ORIGINAL POST Thursday evening
This Saturday will be interesting when it comes to the precip type as we will see mixed precip, although there is a chance for more snow than the models are showing. The warm air in the upper atmosphere will be an issue as well as the exact position of the low. Any deviation either in temp or position of the low will drastically change my forecast. Here's my forecast:
TIMING: Saturday morning through later Saturday afternoon. Those in the south will have precip sooner as the system moves NE.
PRECIP TYPE: The precip will start as snow with some isolated strong bursts. Later in the afternoon the change over to sleet and rain will occur. Those in S MD could see a change to all rain while those in central MD should see sleet and closer to MD/PA line the precip may stay all snow. Again, a deviation in the temp and/or position of the low would give us more rain or more snow. My hunch at the moment is for more snow.
ACCUMULATION: This is assuming the position of the low stays where I think it will. S MD could see about an inch of snow; central MD 1-2 inches of smow and ice accumulation, and N MD 2+ inches .
I will have another update later Friday. Follow me daily on Twitter (@wxmanmd) for weather tidbits and updates.
UPDATE Friday evening
Looking at the latest data and radar I am sticking with what I wrote last night. Those west and north of Baltimore could see a couple inches of new snow while crossing into PA we could see over 4 inches of new snow. Those in S MD should see snow but little to no stickage, an inch or less before you see all rain.
Keep in mind though that any shift in the location of the coastal low will change everything. I'll keep an eye on it Saturday morning and will update as necessary.
