THE HEAT IS GONE AS WE HEAD INTO A TYPICAL OCTOBER WEATHER PATTERN…

The weather patterns in October can sometimes be quite benign. Some of the most precipitation-free patterns have occurred in October. The reason is that in October, thunderstorm frequency has decreased but the storms of the colder season have yet to begin. Also, drier air masses with origins in Canada usually encompass large areas of the country in October. The tropical air masses are surpressed further and further southward. Now, with all that said, it does not mean that there cannot be some weather excitement in October. Sometimes, there are significant low pressure areas that traverse the United States bringing heavy precipitation and some severe weather. The current weather pattern is very typical for October but there are some complexities that are causing the models to have some difficulties coming up with solutions. The front that moved through yesterday (Sat) has become stationary well to our southeast over the coastal waters off the Carolina coast. A wave of low pressure is expected to ride along this boundary but the models keep us dry for the most part. High pressure should bring us nice weather during the mid-week period but another system will be approaching which could bring some wet weather later in the week. The tropical Atlantic remains quiet as hurricane season winds down. Check back in on Monday for an update.
