Albedoman Posted January 31, 2020 Share Posted January 31, 2020 Well, nothing better than tracking legit t- storm chances in February rather then tracking GFS 10 day fantasy snow storms in a miserable snow producing pattern. Lets see if we can get flood warnings to t- storms in this crazy pattern since there is way more more warm air available to produce flooding rains and t-storms than cold air to produce heavy snow. Lets start off this topic by discussing this afternoons Mt Holly discussion about the triple point threat- always a severe t-storm in late April for us when we get into this situation. Lets see if we can manage some serious discussion about this particular threat along with above normal temps. Time to get off the snow-deprived train. By Friday, a kicker shortwave will ride southeastward across the Plains and finally push the stalled trough along. At the surface, this will translate to a final push as a more noticeable surface low forms across the Southeast and pushes up the I-95 corridor Friday, with the triple point moving directly over our area. This will not come as anything different than what we`ve seen thus far this winter with another unfavorable storm track for appreciable snow fall. No significant snowfall is forecast for the next seven days. We`ll just have to maintain patience for now. Link to comment Share on other sites More sharing options...
Albedoman Posted February 2, 2020 Author Share Posted February 2, 2020 Latest Mt Holly discussion-----------------Thursday night into Friday the low over the central United States will finally swing east and take on a negative tilt. The ECMWF, GFS, and CMC all show slightly different solutions here. The GFS has surface low pressure heading northeast over the coastal plain of NJ. The ECMWF has the low heading northeast towards Ontario. The CMC is a hybrid of the two. Either way, wet weather looks to persist into Friday. The latest run of the GEFS shows a widespread 1 to 2" possible for the Wednesday through Friday period, while the EPS run has totals closer to two inches. Saturday, drier weather will return with another upper level low approaching from the west. Potential for some good flooding at least Link to comment Share on other sites More sharing options...
Albedoman Posted February 5, 2020 Author Share Posted February 5, 2020 as per Mt Holly this morning--- we track since no big snows seen as of yet Due to the heavy rain falling on top of already wet soil we could certainly have some nuisance flooding and significant rises on local area small rivers and streams. If widespread rainfall totals reach or exceed 2 inches then additional flooding would be possible. Given that the axis of heaviest rain may occur near and especially east of I-95, held off on any flood watches. Event rainfall totals are forecast to be 1.5-2.5 inches with local amounts close to 3 inches. In addition, at least some guidance shows a little instability developing primarily across portions of Delmarva early Friday morning as the surface low passes nearby and ahead of the cold front. The soundings look on the moist side which may result in rather limited instability, however given the robust wind fields this will have to be watched. Some high-resolution guidance suggests that Delmarva could be on the northern extent of a possible squall line. Given less than ideal instability forecast for lightning production, opted to leave a thunder mention out for now. The greater chance for some thunder looks to be south of our area.

Only wind gusts with the front and a 90 second downpour. At least it snowed after the front cleared up this way. please go back to school. We did have convection. You can have convection without producing thunder and lightning. There were severe t- storm warnings issued and an EF1 tornado . You do not need thunder and lighting to create convection. Why must you insist on challenging me? Do have nothing better else to talk about other than wishing for a snow storm? Convection – When warm, moist air near the surface rises to be above the heavier cool, dry air this is a form of heat transfer or convection. The rising motion typically cools the air. As the air cools, it reaches the dewpoint and all of the moisture in the air condenses– forming clouds. Depending on many factors, these clouds can form rain and even thunderstorms. The process of falling rain is caused by convection. Dry Convection – The type of convection not associated with storms is called dry convection. This occurs when warm air at the surface rises to be above the cooler air overhead. Because there is no moisture, this typically doesn’t have cloud cover associated with it.

We all have our own thoughts on this fickle thing called weather, and everybodys thoughts matter. We don't want this site to go back to the way is was.
