Radar is showing some bands of rain or showers moving from west to east across the region, so I thought a simple wording of “rain at times” would work out for the afternoon.
In the middle of an unusually warm weather pattern for the middle of January, we should see a few episodes of rain during the day and early night. None of the rain is expected to be heavy because the bulk of it will be associated with a warm front that will be pressing northward through the mid Atlantic states.
One obviously glance at the national radar mosaic early Friday is showing where the bulk of the steadier and heavier rain is headed, which is through the Great Lakes region and into Canada.
Temperatures should be no higher than the upper 40s Friday afternoon, due in large part to the extensive cloud cover which will be present. Friday night, after the spotty rain comes to an end, some fog is likely to form.
The upcoming weekend will be warmer, but we must be cautious about Saturday.
The danger is that we could be too warm Saturday afternoon. We aren’t expecting very much wind flow coming from the east, south, west or any kind of direction. Therefore, whatever low clouds and fog develop around the area late Friday night could have a very tough time breaking for some sunshine Saturday.
Therefore, in a worst case scenario, daytime temperatures may be no higher than the lower 50s in Baltimore (even though we have 61 at the present time). We have a much greater level of confidence, though that it will be in the mid 60s on Sunday.
