SPRING ARRIVES: The spring season has officially arrived! This morning at 5:29 a.m. marked the vernal equinox. This is a time of the year in which the length of day and night are nearly equal and the sun’s rays strike most directly near the equator. The earth rotates at an angle as it orbits the sun and as we approach the summer solstice, the sun’s rays will begin to strike the northern hemisphere more directly. Therefore, seasonality doesn’t necessary relate to the earths distance from the sun. In fact, the earth is farthest from the sun during the month of July. The Aphelion as it’s called, will happen this year on July 3rd, when the earth is at a distance of 94,505,901 miles from the sun; an equivalent of 35,528,535.2 laps around Talladega!
WARMER TEMPERATURES: The temperatures are on the rebound and since clouds have remained limited, we could see upper 70s this afternoon. Some of the warmest weather today will happen in states like Texas and Oklahoma where highs will reach into the low 90s! Our area will experience 80° temperatures tomorrow, which is near record territory.
PRACTICE SUN SAFETY: Because of the higher sun angle it is important to practice sun safety as we enter the spring season. The UV index will be in the moderate to high range over the next several days so don’t forget to add SPF30 to the out the door checklist! During the warmer season remember the shadow rule: If your shadow is shorter than you at the horizontal, you are being exposed to higher UV radiation.
WEDGE OF COLD AIR THURSDAY: We will have a chance for a few spotty showers with a weak front on Wednesday; however, Thursday may be a more impactful day with respect to the comfort department. A classic wedge setup looks to develop as cooler air gets channeled along the Appalachians and enters east Alabama. This will likely setup a big temperature spread, with highs only in the 50s to the east, with 60s far west.
FIRST ALERT UPDATE FOR SATURDAY RAIN/STORMS: Our next big rainmaker will arrive this weekend as a cold front enters the state on Saturday. Plan on rain for Saturday, along with some embedded storms. Some of the storms may be strong and we will be monitoring for that potential over the next few days. This will be a slower moving system and some wrap around showers and clouds could impact Sunday.
