Houston Weather for Monday, Mid-Morning Update: Drizzle Code, Rain Chance Up to 45 Percent - and Tonight's Low Jumps to 57.7

Monday is not following the morning script. At the mid-morning read of the station's own weather feed, Houston sits at 61.8 degrees under an overcast sky, and the day's code has turned to drizzle with the precipitation figure up to 45 percent - the highest reading of the day so far, above both the 41 percent of the early files and the 60 percent first carried overnight before it fell. The high holds at 67.8. If the morning file's light rain was a chance, the mid-morning file's drizzle is a presence: not a washout, but a damp gray day that is actually happening.

Tonight is where the forecast moved most. Monday's low has jumped to 57.7, up from 53.9 in the morning file and 57.1 at 3 a.m. - the coldest-night-of-the-week story is off. A warmer, cloud-held night replaces it, and Tuesday's low is warmer still at 59.9. Tuesday also carries the week's most aggressive weather code, heavy rain (65), though at a precipitation figure of only 13 percent - a code to watch rather than a promise, and the desk will file what the feed says as it firms up.

The rest of the week reshaped itself around the change. Wednesday has lost the clear sky the morning file promised: it now reads light drizzle (code 51), a high of 76.1 and a rain figure of 13 percent. Thursday is the warm, dry day instead - 78.0 under an overcast code with a figure of 2 percent - and Friday is now the week's clear day, code 0, at 76.5 with no rain figure at all. The weekend runs warm and mostly dry: Saturday 79.9 and partly cloudy, Sunday 76.6 with a shower code and an 18 percent figure. Monday's lesson, at mid-morning: dress for drizzle today, and put the heavy jacket back - tonight is not the cold one anymore.
