Temperatures Up Later This Week
Showers were widespread south of IH-20 on Monday, with scattered activity likely Tuesday and widespread showers and thunderstorms back for Wednesday.
Rain fell in Tyler about 11 a.m., with the city picking up 0.05 inch and the airport 0.26 inch.
Heavier amounts fell across the south, where Nacogdoches received 1.03 inches. Closer to the Gulf Coast, some stations southwest of Houston received more than two inches.
Friday’s cold front began retreating northward as a warm front. At the same time, a strong flow of Gulf moisture was being drawn northward in advance of a storm system forecast to cross Wednesday.
Monday’s temperatures averaged near those of Sunday, and were about 6 degrees below normal.
Temperatures on Tuesday should run about 7 degrees warmer, with temperatures on Wednesday a couple of degrees warmer, still.
Low readings Monday morning were 10 degrees or more higher than those of Sunday, and were determined by when a mid-level cloud layer arrived over a station.
High readings Tuesday should run from the high 70s to lower 80s, with 80-degree readings likely to be general Wednesday.
Winds on Monday were light and variable overnight, and southeasterly at 5-10 mph during the day.
Southeasterly to southerly winds should increase in velocity both Tuesday and Wednesday, with a wind advisory possible for Wednesday.
Tyler’s highest sustaining wind Monday was southeasterly at 10 mph, with an average velocity of 5.2 mph. Sunday’s average wind velocity was 3.9 mph.
Monday’s average relative humidity was 71 percent, with higher values likely both Tuesday and Wednesday. Sunday’s average was 57 percent.
Tyler’s high temperature of 69 came at 6:16 p.m., following the day’s low of 61 at 3:10 a.m.
Showers should be scattered in the area Tuesday afternoon. The moist air will remain, temperatures will be somewhat warmer, and minor impulses in the southwest wind flow aloft will continue to cross. These last should not be as strong as were Monday’s.
Areal coverage Tuesday should be about 40 percent, but should extend farther north than those of Monday which were confined generally along and south of IH-20.
Amounts Tuesday should run under one-fourth inch.
A squall line is forecast to set up Wednesday afternoon ahead of the next cold front. This should bring showers and thunderstorms to much of the region, with areal coverage approaching 75 percent, and amounts of between one-half and one inch.
With the line forecast through Tyler at late-afternoon, there is the chance for some of the thunderstorms to reach severe limits.
The cold front should become stationary south of the region Thursday. Humidities will be lower, but temperatures are not likely to be affected much.
In fact, the dry air mass should send daytime readings close to 90 late in the week.
Another storm system is likely late next weekend ahead of a stronger cold front. This will return rain chances, and probably introduce below normal temperatures for early next week.
