Storm Systems Usher In Cooler Weather

Temperatures Will Struggle To Reach 60 On Friday

So far this month, the temperatures have been above average for the most part.  There were thunderstorms this time last week with some of them being strong or severe.   The thermometer has been kind by keeping the mercury at more comfortable levels.  However, that is going to change a bit on Friday and carry over into the weekend.

The diurnal range of temperature this month in South Plainfield has been about 41 degrees with a high of 82 degrees and a low of 41.  The average temperature is just under 60 degrees.  On  Friday morning, the temperature bottomed out at 49.4 degrees after reaching a high of 64 on Thursday.  Winds still remain brisk.  Top wind gust on Thursday was 8 miles per hour while so far on Friday, there has been a 6 mile per hour gust.

After dealing with some rain on Wednesday, and windy and cloudy conditions   on Thursday, the barometric pressure is on the rise.  Earlier this week, the pressure dropped to 29.27 inches of Hg.  At the time of this report, the barometer had risen to 29.91 inches of Hg.  There was only a little bit of rain on Thursday, and so far no measurable precipitation on Friday.  The two storm systems that impacted our area the past two days brought in change.

The change is in the form of more fall like conditions.  After seeing high temperatures climb into the upper 60s to low 70s for the past week, the mercury will have to fight to just get into the 60s on Friday afternoon.  Add a west wind that will be blowing between 20 to 30 miles per hour during the day, and 10 to 20 miles per hour at night, it will be a bit chillier than it has been.   While we will not have conditions for radiational cooling overnight, temperatures will fall into the mid to upper 40s.

Skies will be clear and sunny on both Saturday and Sunday, but temperatures will struggle to reach the mid 60s.  Finally by the beginning of next week, we will see a warm up with temperatures reaching the mid to upper 60s with a chance of some showers on Tuesday.
