In South Carolina, folks are enjoying a streak of unseasonably toasty weather at the beginning of the week.  Y'all are going to want to reach for your sunscreen to block the UV rays and maybe even a pair of shorts as South Carolina is basking in warm temperatures. While today is sure to be a scorcher with temps climbing towards the 80s, it doesn't seem like fun will last for long as things will change as time goes on.

            Tomorrow will probably be a bit more gloomy and cooler, in the upper 50s, as a cold air mass is expected to push through during the day.

        As for tonight, there will be plenty of sunshine filling the skies and fog that might be hanging around in the early hours will vanish before noon. The reason all this is possible is because of a strong high-pressure system that will live over New York and push southward along the Appalachian Mountains.

        As the week unfolds, expect temperatures to climb back up, reaching close to 80 degrees from Thursday to Sunday. Wintry systems will continue to slow down, adding to the atmospheric moisture and leading to a rainy weekend.

            Keep your umbrella close by as a passing disturbance to the north may cause scattered showers late in the day.

        The transition from warm to cool and back to warm is all due to the movement of air masses. For those unfamiliar, cold air mass into the region blocks the passage  of warm air. When another warm air mass arrives, the cold air is squeezed out.  Is it birthday cake or is it thunder?  Answer: It is neither because the warm air masses will continue to roll in, and we’re in for some hot temperatures for about the next week, with  lots of clouds and rain.

   The change in weather is due to something called cold air damming.  This is where the cold air mass is blocked by the Appalachian Mountains, which is why it is also going to be colder in the north.  Expect clouds to roll in in the mid to upper 40s.

        Another cause for a change in weather is a strong high-pressure system which will push southwards.  This will mean a cool evening for Wednesday with a chance for rain in the evening.

        This pattern will continue for the next week.  Expect rain for the next week, especially towards the end of the day.  Be sure to check your local weather forecast to keep updated on the latest weather conditions.
