HD Widgets has it. There's 4 choices in 4x1 too. Small header, header left, header right, and smaller header.
Smaller header displays the most info: todays forcast (picture) on the left, clock in the middle with date below, on the right is Location, current temp, High/low temps, and todays forcast text (chance of storms).
The other choices only display a weather pic, temps (current, high, low), but they have a larger clock (no date).
