THE OCTOBER HEAT WAVE CONTINUES THROUGH THE WEEKEND… SOME MUCH NEEDED RAIN IS A POSSIBILITY ON MONDAY AND TUESDAY… TROPICAL STORM KAREN APPROACHES THE GULF COAST… OVER 40 INCHES OF SNOW FALL IN SOUTH DAKOTA

There is a lot of weather happening right now in some parts of the U.S., despite our tranquil weather pattern here in the Mid-Atlantic states. Our weather this weekend will be a continuation of the warm and sunny conditions that we’ve seen the past few days. However, changes are on the way. A powerful storm system for this time of year now centered in South Dakota will drag a cold front through our part of the country Monday and Tuesday. This will be our first chance of significant rain in a very long time. I heard one TV meteorologist say that if we don’t get much rain from this system, we will be entering a drought. The rainfall may even he enhanced by whatever is left of Tropical Storm Karen, which is a weak storm now heading towards the Gulf Coast. Let’s hope that we do get some much needed rainfall. Some thunder is possible, but forecasters don’t think that severe weather is likely across Hampton Roads from this event. The trend in temperatures following the frontal passage will be downward putting an end to the above normal temperatures that we’ve seen lately. Karen has stayed weak because she is struggling against strong wind shear. Right now her thunderstorms and deep convection are well to the south and east of the center.  Although it is possible that she could intensify sligthly before making landfall, she will probably be remembered more for the rain than the wind. The visible satellite shows that there is really no deep convection around the center of the storm which should mean that she stays weak. The storm that brought heavy snow to parts of the Plains States also caused strong thunderstorms and tornadoes to Iowa, Nebraska and South Dakota. In some autumns, there is another tornado season as the jet stream becomes more active and the air masses begin to clash across the center of the U.S. It’s not usually as bad as the spring tornado season, but sometimes tornadoes can be quite destructive at this time of year. That’s it for now. Enjoy the summer-like weather this weekend.
