SNOW ALERT! Snow amounts increasing due to radar coverage

Snowfall for the next system has been upped by the NWS. Many areas west of I-95 have been sent to a Winter Storm Warning. It appears that 4"+ of snow will fall in these regions. Higher amounts will occur near and in the mountains.

Snow is now likely to break out near daybreak in the DC metro area. Snow will fall and become heavy at times west of I-95.

Best I can tell from what i am seeing.

A line from Roanoke, to Harrison burg to Leesburg through middle of Frederick County Maryland will see the most snow.

yes.. I kind of fell asleep at the wheel on this one! Again.. snowfall I think will generally be 3-6" east of the immediate piedmont and 4 - 8" in higher elevations.

This has a very high likelihood too change!

Messy mix probable Thursday and Thursday Night

There is a fairly strong chance that a mix of snow, rain,freezing rain, and sleet will be occurring Thursday and Thursday night.

This is especially true of the Piedmont and mainly west of I -95. Areas of higher elevations could see some accumulating snow before a mix also comes into play there. Not a lot of time so this will be all for now! Please note, that, unlike the last 2 storms, more cold air is already in place before the start of the system.

Not much snow- Potential later this week - brutal cold coming!

Just not cold enough and a storm that will not get its act together until too late! So we will see rain and many places will likely see a mix at some point overnight, but accumulations are not likely. I could see a dusting and I still feel a bit worried about abandoning accumulations, but i am not getting the Forecast Model support. I will need to watch maps today and this evening to be sure I do not have to reverse course, but again, this winter, we have to call off a real snow alert and just make you aware of the possibility for some snow later tonight.

This week will be a busy one with another possible winter system Thursday/Friday and then a brutally cold snow this coming weekend! Highs may stay in the teens to even single digits in the mountains. Systems could be poised for more snowy concerns next week as we stay pretty cold!

So the key here, less chances of snow.. a seasonable weather week, another chance of wintry weather Thursday and Friday followed by the coldest cold of the season!

Hang on for the bumpy ride!

More later!

Snow threat still there for Northern VA and Maryland - Not enthusiastic about a big storm.

Trends on models have been to get this storm together later than would be needed for a larger snowstorm in the area. that being said, some details are obviously not know, and this one has a chance to surprise us. The forecast models have shown a move further east and north with the precipitation. This trend may continue or could be wrong. I am certain some precipitation will fall tomorrow and tomorrow night. I am also fairly certain areas will see snow after some rain for a while. I am not certain if much more than 1  to 3 inches would fall. Areas likely to see snow after a mix would actually be along and just east of I 95 north of Fredericksburg and this would happen tomorrow night. Areas west of I 95 north of Fredericksburg and just up and east of the Piedmont could see a 1 to 2" snow. If models continue to trend unfavorable for heavier precipitation, rain may not turn to snow until right at the end. On the other hand, there may be some more adjustments

So I am not enthusiastic about a big storm, and I am concerned by the trends. They could reverse and we could see more snow so this one is going to be a tough one!

More to come!

Continued chance of wintry weather Sunday.. details are fuzzy!

There will be a storm and there is the distinct possibility of snow, but the temperatures at the surface may just be warm enough that accumulations become somewhat limited. There may also be a lot of forecast model issues at this time that are causing me to think less of the storm for the time being. The possibilities still run the spectrum from rain most place to more snow, and the lighter or heavier amounts. Now it looks fairly certain there will be some wintry weather in the region, the amounts and impact are way too early to detail.

Next week looks cold and also has another potential snow threat later in the week. We are entering an active winter pattern!

Potentential Significant Winter Storm Sunday into Monday!

Situation will need to be monitored but it appears a strong Nor'easter may be ready to blast the region with Heavy precipitation Sunday into Monday. Preliminary model output does put areas in a risk for significant wintry precipitation. This has shown up several times on models in the past and then changed dramatically so I will continue to monitor!

All for now!
