Good afternoon,

We now share the seasonal Maryland Climate Bulletin for winter 2024-25.

You can access the winter Bulletin from the following link:

https://www2.atmos.umd.edu/~climate/Bulletin/bulletin_mdsco_win25.pdf

Points to highlight are:

1) Winter 2024-25 was colder and drier than normal (i.e., 1991-2020 averages) in Maryland, with warmer and wetter-than-normal conditions in February, but colder and drier-than-normal conditions in January and December.

2) The mean temperature was colder than normal everywhere in the state, especially in southeastern Baltimore and Harford counties, Kent, Queen Anne’s counties (2.4−2.8°F below), Caroline County, and portions of Talbot, Dorchester, Wicomico and Worcester counties (2.2‒2.6°F below), and Garrett County (2.2‒2.4°F below). Precipitation was below normal over almost the entire state, particularly in Harford and Kent Counties, portions of Cecil and Queen Anne’s counties (4‒4.8 inches below), and counties in the Piedmont (2.8‒3.6 inches below). The regions with the maximum deficit over the state's northeast received around 55−60% of their climatological winter precipitation.

3) The partial water year 2025 (October 2024 − February 2025) was below normal across the entire state, especially over Harford, Kent, Queen Anne’s, and northern Caroline counties (8−9 inches below); this region received 45−50% of its climatological water amount. The counties in the central and western Piedmont, as well as Washington and eastern Allegany counties, received 50−55% of their normal water amount. Somerset and Wicomico counties received 70−75% of their climatological water amount, while Garrett County got 80−95% of its normal water amount.

4) Statewide mean temperatures showed that winter 2024-25 was the seventy-second coldest winter (or fifty-ninth warmest) since 1896. Statewide maximum temperatures indicated that this winter was the sixty-ninth coldest (or sixty-second warmest), while statewide minimum temperatures showed this winter was the seventy-fourth coldest (or fifty-seventh warmest) winter on record.

5) Statewide precipitation revealed that winter 2024-25 was the nineteenth driest winter and among the ten driest for four counties. It was the seventh driest winter for Carroll and Harford counties and the fifth driest for Kent and Queen Anne’s counties. This winter was also the twelfth driest for Talbot and Washington counties and the eleventh for Baltimore and Caroline counties.

Please take a look at the bulletin for more details, including the winter century-plus long trends.

The bulletins are issued to monitor the state's recent surface temperature and precipitation conditions in a simple format, allowing Marylanders to better understand regional climate variations.

Please help disseminate this bulletin.

This might come as a surprise to us weather weenies as we want 14 day forecasts to be quite accurate but April 1^st snow storms are very rare. Thus, there are two competing forces here, and since the rareness of a 12” snowfall in late March / early April is greater than the accuracy of a 13-day forecast, there is still good chance that we may not get that 12” snow fall a fortnight hence.

Dr no ensembles say likely at least if you look at the Sunday-Monday time period.

How we lookin?

Not dead yet. EPS still has one member (of 51) giving the DC area >+ 3" of snow/sleet during the next 10 days.

According to "me", Baltimore's winter through February is the 71st best of 132 winters (47th PCTL). So far, it has had 29 days with mean temperatures of freezing or below, 12.7" of snow, and 12 days with at least an inch on the ground. DC's winter is 66th best of 132 winters (51st PCTL). So far it has had 20 days with mean temperatures of freezing or below, 14.9" of snow, and 13 days with 1" or more of snow on the ground. Hope you're enjoying such a mediocre (near the median) winter.

While the median forecast snow/sleet from the ECMWF EPS is about 0.1" for most of us, the 90th PCTL outcome shows the 2" line just southeast of many of us.

Maybe the Euro AI is only based off of data from 2017-2024 when it basically never snowed, so it can't handle a TUCKED FOLKS.

I know you're joking, but I believe it trained on selected years from the 40-year ERA5 reanalysis, which covered 1979 - 2018. A reanalysis blends model output with observations. The resolution of the training data set is 1 x 1 degrees, so relatively coarse.

Almost

2" here as of 6

February 11

Just fell below freezing here (31.9) and on cue, despite the disconnect between air temperature and the surface, the driveway is beginning to cave. Moderate snow.

Happily not wasting any of my precious QPF under this nuclear sun angle. Sorry VA

Yes, the current sun angle of 32.6 degrees at my location and time is more than 11 degrees higher than it would have been on the 21st of December at the same time.

Not sure that is a trend. More of a wobble. I still like that stripe to come a little north at game time. But splitting hairs at this point. We will know in about 24 hours

The precipitation distribution wobbled back to what it looked like in the 00 UTC run.

https://www.meteor.iastate.edu/~ckarsten/cobb/cobb.php?model=nam&site=kdca

Here is a site that a few of you may not be aware of. It is useful for determining the timing of precipitation onset, examining rates, and looking at model temperatures from the NAM and GFS. For example, the unrealistic snow amounts from 12-km NAM are not just due to its convective algorithm but are partly due to the low temperatures it is forecasting.

Biased a bit high because it counts sleet as snow?

Percent of EPS members giving the Laurel area at least 12" (dash-dot), 6" (dash), 3" (dotted), and 1" (solid) of snow/sleet during the 9-14 day period before 00 UTC February 15.

February 5

On a more uplifting note:

"February 5th is National Weatherperson's Day.

The day commemorates the birth of John Jeffries in 1744. Jeffries, one of Americas first weather observers, began taking daily weather observations in Boston in 1774 and he took the first balloon observation in 1784.

This is a day to recognize the men and women who collectively provide Americans with the best weather, water, and climate forecasts and warning services of any nation."

January 31

Day 8 - 15 has potential. Note first plot shows percent of ensembles with >1" of snow/sleet/ice, while latter shows pct > 6" ...

Sorry for the confusion, these rankings only consider snow that falls during the fall and early winter (through January 31). I'll update at the end of February.
