• After witnessing the continued decrease of involvement in the SpotterNetwork staff in serving SN members with troubleshooting issues recently, I have unilaterally decided to terminate the relationship between SpotterNetwork's support and Stormtrack. I have witnessed multiple users unable to receive support weeks after initiating help threads on the forum. I find this lack of response from SpotterNetwork officials disappointing and a failure to hold up their end of the agreement that was made years ago, before I took over management of this site. In my opinion, having Stormtrack users sit and wait for so long to receive help on SpotterNetwork issues on the Stormtrack forums reflects poorly not only on SpotterNetwork, but on Stormtrack and (by association) me as well. Since the issue has not been satisfactorily addressed, I no longer wish for the Stormtrack forum to be associated with SpotterNetwork.

    I apologize to those who continue to have issues with the service and continue to see their issues left unaddressed. Please understand that the connection between ST and SN was put in place long before I had any say over it. But now that I am the "captain of this ship," it is within my right (nay, duty) to make adjustments as I see necessary. Ending this relationship is such an adjustment.

    For those who continue to need help, I recommend navigating a web browswer to SpotterNetwork's About page, and seeking the individuals listed on that page for all further inquiries about SpotterNetwork.

    From this moment forward, the SpotterNetwork sub-forum has been hidden/deleted and there will be no assurance that any SpotterNetwork issues brought up in any of Stormtrack's other sub-forums will be addressed. Do not rely on Stormtrack for help with SpotterNetwork issues.

    Sincerely, Jeff D.

The old day five wave is now upon us, ushering in cold air. Subtropical moisture feed is interacting with northern and southern stream vorticity. Ice pellets developed in Memphis as precip ended. Snow is falling above 2000ft in NW Tennessee. Looks like southern stream energy will produce an overriding event with a 10-50 mile wide snow band from extreme nother Alabama to New York City.

This will be an atmospheric snow. 1-3 inches may fall but will melt on contact with the surface. In northern regions like Baltimore to New York City, expect 1- 1 1/2 inches on car tops, a few patches on the ground in shaded areas at sunrise Wednesday.

This is the first volley. Fun times.

I should add that the last post was 70% model, 15% climatology, and 15% experience. The great x-factor is reality. That's why we chase storms. That's why we look out the window. Can this event, under or over perform? You bet ya.
 
Unnecessary chatter. I think that showed up in my evals a time or two, that being said, we indeed had 1-2 inches of snow on car tops.. I apologise for image quality. I have a better camera.

The surface accumulation was greater especially south into Tennessee. It over proformed in those areas with 1-3.

Tommorow we will introduce black ice, or freezing rain, from Western NC to Maryland. NW Baltimore suburbs are in question. WAA will erode these conditions. Timing will dictate more or less.

A band of snow and mixed precip with the next wave, the old 10 day wave. Euro further south. GFS still has a "cutter" into Ohio. 84-96 hrs. Models still not in agreement..

Great snowstorm for eastern/central Kansas , central Missouri, Illinois, Indiana and Ohio. A 75-100 mile band of 3-6 inches with locally higher amounts. This is the old ten day wave.

Northern Virginia, extreem NE West Virginia and Maryland will be under a developing CAD. This will narrow the band to 30-50 miles. I know this will be a nightmare forcast for the local meteorologist in this area including the 1-95 corridor. They most likely have been pulling thier hair out. There will be a lot of nowcasting. More to come.

As an aside, I think I speak for everyone that our thoughts and prayers are with those who experienced the severe weather and tornadic distruction with yesterday's frontal passage in Florida. This volatile pattern will persist.

Nice moderate snow band. 16Z surface plots show surface vortex slightly North in southern Oklahoma. Freezing rain in central Kansas. WAA underway. Freezing rain in Oklahoma further south than prog. Love the 6 hr bust....

Disclamer. Precipitation at the surface and aloft. Precip below 1500 ft not depicted, ie Zl-. This can be significant.
