12/28 Final Call

Big Winter Storm Commencing!

What?

Major Winter Storm

When?

From Tonight Through Late Tuesday Night, though bulk will fall next 24 hours

How Much?

I have my final call map here: http://www.midatlanticweather.com/images/2_28_2005_F.gif

Some Locations:

Hagerstown: 8-10

Dulles: 8-10

Washington DC: 6-8

Fairfax: 8-10

Charlottesville: 8-10

Lynchburg: 4-6 some Freezing Rain

Roanoke: 8-10

Wytheville: 8-10

Danville: 1-3 Freezing Rain Threat

Richmond: 1-3 To Rain

Fredericksburg: 4-6

NOTE: These could be underdone! There will be Thundersnows tomorrow and I could really be
under doing the amounts! I am playing it safe with eth QPF from models Also, the area expecting a large mix.. if it is snow.. that will be much higher!

Concerns:

1.
Models suddenly warmer and less precip. Is this true? Doubt it looking at Radar.

2.
Really, my concern is that the precip totals could be too low!

3.
May see a regeneration of snow again tomorrow night as the Upper level system comes through

4.
Winds will start to be an issue tomorrow night… This could mean we get to Blizzard Conditions? That will need toe be assessed tomorrow and more likely north of our region of the country

5.
Far western VA and Maryland (western facing slopes)could see a serious amount of snow tomorrow night into Tuesday from wrap around and that upper level disturbance.

All for now.

Please join the forum and give your updates on the storm!http://www.midatlanticweather.com/bb/

2/25 BIG Storm Monday Could Bring BIG SNOW!

Big Storm Monday likely to start as Snow for areas central and west and may stay that way west of I-95, especially higher elevations!

 

I will do a full update later tonight or early tomorrow morning! Mountains, get ready! West of I-95 for the Northern half of the area! Stay alert!

 

If, by chance, things line up, there could be locally 1 to 2 feet of snow in areas! The higher your elevation, the more concerned you need to be!

 

More to come!

 

All for Now!

2/24 DC/MD/VA SNow Final Call

Snow Alert Final Call

What: moderate to potentially heavy Snow event.

Where: Today we had a major Shift North. Southern VA likely to see rain. Northern Virginia and Maryland will see Moderate to heavy accumulations

Final Calls for some select locations.

Dulles – 4-8

DC – 3-6

Baltimore - 4-8

Hagerstown - 6-10

Charlottesville – 3-6

Orange – 3-6

Fredericksburg – 3-6

Spotsylvania – 3-6

Ashland – 1-3

Richmond – 1-3

Roanoke – 1-3

Lynchburg - 2-4

See Map: http://www.midatlanticweather.com/Images/2_24_2005_f.gif

When: Starting: 2 am Southwest. Overspreading the north by 9 am. Expecting heavier snow between 10 am and 3 pm .. may see a lull and then a regeneration of light snow tomorrow evening and night in the North.

Concerns:

1.
Limiting factor may be the convection to our south

2.
Mix may make it to DC suburbs south of town

3.
Could see cold air wrap into system and give some snow back to south central regions

4. Snow deformation line/wrap around possible Central Maryland into Northern Virginia

2/24 Second Guess:Note Shift North

Note the shift to the North. This may not be done.

First Guess

2/22 DC/MD/VA Snow Alert for Thursday

Snow Alert

 

What?: Moderate Snow Event

Where? Most of Virginia and Maryland

When? Thursday

How Much?

2-4 Northern Virginia and Maryland areas

4-8 Central Virginia

2-4 NC/VA Border with Sleet and Freezing rain involved especially coast!

Could see heavier amounts of 10 inches in parts of the region!

 

Accumulations vary North to south and not east to west in this event. (Further north the less the amounts)

 

Concerns:

1. Northern cut off of precip could be sharp so Northern Maryland could see far less
2. Higher Ratios could up the Northern Virginia and Maryland amounts.
3. Precip could come further north than what models show.. but not by much!
4. Low may not come far enough north (low risk, but there)

 

OF NOTE: Cold air is not a big issue with this event as the last 2 events, thus snowfall much more likely in this event

 

Hope for Snowfall maps later tonight!

2/20 Snow Alert

Snow Event Diminished

What: Light Snow Possible
Where: Northern VA and Central MD Immediate Piedmont to areas just east of I-95
When: Sunday afternoon through Monday Morning
How Much: At most, I could sonly see a 1-3” snow based on models. Areas really DC to Dulles To Baltimore and north have the greatest threat of accumulations with higher amounts north. Isolated 4” near the PA/MD border would not surprise me. See http://www.midatlanticweather.com/2_22_2005_f.gif
Concerns: It appears warmth will really work fast to erode cold air. I will continue to monitor. Seems really cold, but strong southerly winds are at play here so a quick turnover would not surprise me!

Snow/Wintry Event More Likely

What: Light to Moderate Snow
Where: Northern VA and Central MD Immediate Piedmont to areas just east of I-95
When: Sunday afternoon through Monday Morning
How Much: Refer to http://www.midatlanticweather.com/2_20_2005_.gif looks like 2-4” immediate Piedmont North of Charlottesville up through Maryland. 1-3” I-95 areas Fredericksburg and north.
Concerns: I hope I am not overdoing precip. Still could have to shift this north if warmer air is more powerful.

2/18 DC/MD/VA WInter Weather Alert

Winter Weather Alert. Possible storm..

What: Looks more likely that a Small to moderate snow will affect parts of the region.

Where: the Northern areas of Virginia and Maryland especially piedmont areas

How Much: A general 1-4 inch snowfall is possible with some amounts to 6+ inches in the far Northern VA and the immediate piedmont of Maryland. A changeover to light sleet and freezing rain is possible near the end of the storm with plain rain further South and East, and eventually a cold drizzle or light rain most places by Monday Afternoon.

When:
Starting Sunday Afternoon and ending Monday Morning.

Why will this happen, why might it not:

Models are really split on the scenario and this split brings a wide range of solutions. Best bet is a start as a mix of snow and rain to mainly snow northern areas. A quick turnover to rain any outhern areas and a slower turnover north. The idea is that the warm air will not overwhelm the storm before a coastal locks colder air in for northern areas. The coastal is a big factor in this forecast and it may not form. Consistently one model has shown a much warmer pattern and another a colder. Which one is right? If we compromise, I would say not a big storm for many. That is why my range is so large. 1 to 4 inches in the north. I have to say a possible 6 inch plus because if the colder model wins a more significant system could affect the region. One other note, precip amounts on the colder model has been very wrong with storm totals in this region this winter usually favoring more precip than less. I was burned in January and then again the next storm. I have to be more conservative this time. This is my first guess too!

More to come.

02/02 Southwestern Virginia Snow Alert!

Southwestern Virginia Snow Alert!

Between Tonight and Friday Morning, as Much as 8” of snow could fall in the Higher elevations of Southwestern Virginia. Areas specifically west of Lynchburg to Martinsville and east of Bristol and Bluefield. Even at lower elevations as much as 3-6” of snow is possible.

There is also the possibility of mixed rain and snow and some sleet as far north as a Harrisonburg to Frederickburg to Salisbury. Areas south of this line will have periods of Rain and snow mixed (especially at night). Southern Virginia, especially areas close to the above mentioned area of Southwestern Virginia, could see some light accumulations of 1 to 3 inches.

This situation could change and move precipitation more northward or even southward. Models continue to track the systems poorly. Also, cold air is not in great abundance, so whereas the higher elevations of Southwestern Virginia seem Likely to get good snows, lower elevations could mix and be primarily rain at times. This scenario is not easy to predict.
All for now!
