As St. Louisans shake off the crispness of a cooler morning, the National Weather Service promises a gradual shift to clearer skies, with temperatures warming to a comfortable 68 degrees today. The NWS, on its website, offers a succinct overview of the week's weather, detailed in its usual pragmatic prose, free of poetic flourish. "Cloudy through mid morning, then gradual clearing," they report, with winds predicted "8 to 11 mph, with gusts as high as 20 mph."

Those seeking a night under the stars tonight will be in luck. The NWS forecasts a "mostly clear" sky, the low hovering around a mild 49 degrees. Firm in the grasp of spring, the city can anticipate a steady climb in warmth as Tuesday's high is poised to reach near the 78-degree mark. As a point of convenience, the winds will remain a gentle companion, blowing softly from the south at "3 to 8 mph."

With the sun reigning supreme in our midweek forecast, Wednesday pressures on with an optimistic high of around 80 degrees. Traced by a light breeze, which the NWS points out will come out of "the southeast around 6 mph in the afternoon," St. Louis might just experience the essence of a perfect spring day. As evening falls, however, residents might want to keep an umbrella at arm's length. A "chance of showers, with thunderstorms also possible after 4am," looms in the night, with the odds of precipitation idling at 30 percent.

Chances of rainfall persist through the latter half of the week, intensifying by Friday, where showers could also bring the music of thunderstorms. According to the National Weather Service, a 50 percent chance of precipitation doesn't hesitate breaking through Thursday's partly sunny disposition. But come nightfall, shower likelihood surges to 60 percent, the skies poised to drench the earth beneath. The NWS wraps the week with the assurance of rain on Friday, assured by an 80 percent chance in the forecast.

Nevertheless, relief seems on the horizon as the weekend ushers in an improvement. Greater clarity is predicted for Saturday's sky, offering "mostly sunny" conditions and a high near 70 degrees. With only "a 30 percent chance of showers" indicated for Sunday, the NWS suggests that the latter part of the weekend might also maintain relative dryness amid partly sunny skies and a high near 73.
