LONG TERM /MONDAY THROUGH THURSDAY/... Sunday`s cold front is expected to be offshore by Monday morning. In its wake, the deep parent upper trough and its accompanying cold airmass will pivot overhead

Per the mesonet, only the immediate areas along the Bay avoided a freeze this morning. 

We're really starting to see some impressive microclimates emerge. Thurmont dipped to 34 degrees, but just to the northeast Harney at its lower elevation decoupled to 26 degrees.

Westminster at 882' with a low of 38.  And Frostburg in the mountains misses at 36.  Elevation, open water, and urban heat island all doing work around the region.

LONG TERM /MONDAY THROUGH THURSDAY/...
Sunday`s cold front is expected to be offshore by Monday morning. In
its wake, the deep parent upper trough and its accompanying cold
airmass will pivot overhead. Mid/upper-level heights and low/mid-
level temperatures are forecast to be 3-4 standard deviations below
normal per NAEFS climatology (i.e. 850 hPa temps -8 to -13 C 12Z
Tuesday, which may challenge the daily record for the KIAD UA).

Strong cold air advection and a persistent pressure gradient between
low pressure over southeastern Canada and Polar high pressure
building in from the Midwest will lead to blustery conditions.
Despite downsloping northwest flow and peaks of sunshine, high
temperatures on Monday and Tuesday will struggle to escape the 40s.
In fact, some guidance keeps high temperatures in the 30s for most
of the region (coldest Tuesday). Higher elevations will be notably
colder by about 10-15 degrees, and wind chills will be a factor as
well (running 10-20 degrees below the air temps). Wind chills may
not get much above freezing for very long Monday and Tuesday, even
during the afternoon hours as winds gust to 30 mph or more.

With the northwest flow comes a favorable trajectory off of the
Great Lakes. This is expected to result in the first accumulating
upslope snow event of the season (likely begins late Sunday night
and persists into Monday night or perhaps early Tuesday morning). It
remains a bit too soon to speculate on exact amounts, but the first
plowable snowfall of the season is becoming ever more likely along
and west of the Allegheny Front. Some guidance implies possible
warning-level snowfall along the west-facing slopes of the higher
peaks, which makes sense given some instability and moisture
overlapping the DGZ (as evidenced by a high Snow Squall Parameter).

An embedded shortwave and higher FROUDE numbers indicate the
potential for precipitation moving east of the Allegheny Front, with
accumulating snow possible particularly late Monday into Monday
night into the foothills east of the highest ridges. Depending on
the strength of the wave and the amount of available moisture, snow
showers may dot the landscape well into the Piedmont and possibly
even the metro areas Monday night. Although significant snowfall
accumulation is unlikely east of the Appalachians, the cold air and
snow shower potential would be a fitting reminder of the record
Veteran`s Day snowstorm that occurred nearly 4 decades ago.

Hmmm. Doesn’t say Howard, but has everywhere around us?

I believe Howard was already done?  Let me check

EDIT - NW Howard County had their growing season declared over by LWX on Oct 25th

Neither say SE Howard though. Probably just an accidental oversight.
