Dressing up and heading outside in the dark for free candy is a right of passage for most kids, and some adults. Doing it is Baltimore over the past 15 years has proven to be a rather pleasant experience.
11 out of the past 15 years were above normal.
In fact, we had a good run of rather warm Halloweens, six reaching the 70s, and one year it was 67°F but hit 73°F on November 1st.
Consider the normal conditions based at BWI
- High: 62°F (usually 3-4 pm)
- Low: 41°F
The evening temperatures would slip below the high and expect to be in the 50s. But kids dressing up to school and some adults for work would usually fair pretty well in our part of the world.
Now consider the extremes:
Hottest: 85°F in 1946
That capped off a 3-day heat wave (29th=82; 30th=83F; 31st=85F)
Coldest High: 41°F in 1925.
That was a day after the record snowfall of 2.5” on Oct 30th.
The record coldest (morning low) was 25°F in 1966
Surprisingly there is no record of measurable snowfall for Baltimore ever on Halloween dating back to 1880.
The wettest was 1.50” in 1926
Talk about extreme swings!
1925 = record cold after the record snow
1926= record rain.
When I mentioned doing this research on my Facebook page, many people asked the question if there is any relation of this to winter snow. Considering that this is just an arbitrary date on our calendar, there was one other date that popped into mind: December 5th, out date with destiny for first snowfalls of the winter.
So why not compare the two?
So the results….
Wait for it….
The last time Baltimore reached 70°F on Halloween was 2009. That was followed by our record winter snowfall of 77” (lowered by NWS at the end of the season). Now that I got the attention of fellow snowhounds, there rest is important.
Our #3 winter season was 2002-2003 with 58.1” of snow. That preceding Halloween featured a high temp of 48°F, so I am sorry, but there is no connection there. But that December 5th did start our streak of snows for that date with a record 7.4” at BWI.
