Thursday December 20 2018

We have yet another Flood Watch across our area for the widespread 1 to 2 inches of rain. It will begin as showers this morning, then steady rain this afternoon and heavy rain tonight. In addition to flooding, there is another risk some trees can fall over. Especially where winds will be strongest. A Wind Advisory is in place across Delaware and the New Jersey coast for gusts up to 50 mph. But there is something weird about this storm that needs to be explained with all of the other details.


Storm Key (Weird) Notes:

  • This morning: Temps start in the 20s with thick frost.
  • Fog will develop ahead of the rain. Be careful early if you see fog as it could get slick on frozen pavement.
  • Showers develop this morning with more steady rain afternoon.
  • Heavy rain overnight into Friday morning.
  • Temperatures will be in the 30s to low 40s this afternoon.
  • Temperatures will reach near 60ºF tonight. Midnight to Friday morning will be the warmest time (with the heavy rain)
  • Temperatures will fall Friday afternoon and evening. 
  • The storm will end with accumulating snow in the mountains Friday night


Morning Set Up


Morning Radar:

This is another large storm coming up from the Gulf of Mexico, so there is plenty of moist and it will be with us for a few days. Rain will las Friday and perhaps into Saturday morning.

Storm Animation


Looking Ahead: 

There is still a chance for snow or a mix early next week. There is still some confusion and disagreement on the modeling. I think how this strong storm behaves will determine what is left in its wake. I will share more on the potential Christmas Eve/Day snow or rain in my next report.


Temperature Outlook

Most of the next two weeks appears to be near or below average.

The pattern supports a storm within a few days of Jan 1 AND a much colder and snowier pattern in January.


Snow Day Kit

Our ritual the night before a storm is finally in one kit. Maybe if more Maryland kids had this, the storm would reach us 🙂

  • This includes a very soft raglan Tee printed inside out with #FITF AND the check list,  #FITF spoon for under your pillow, ice cube tray with snowflake shapes, chalk, a #FITF wrist-band, a mini SnowStix, and a bag to carry it all in.
  • New Orders are likely to be delivered after the holiday.
  • This will also help us give a free Snow Day Kit to each of the Just In Power Kids.



FITF and SnowStix Stores are now OPEN
