Somerset Weather · Hyper-local Forecast

One row per day: the station's actual high and low in bold, and beside each what every source said. Pick a goal and a cut-off; a green cell is a forecast that landed within the goal, and the top row counts them. The cut-offs are the Scoreboard's: the last forecast each source had issued before the period began, the one it had out the day before, and two days before. The main model is the candidate on trial (L-038).

What the columns are

Actual
What the station measured: the day's high in its window (7 AM to 7 PM) and the night's low in its window (7 PM to 8 AM), the same windows the Scoreboard grades.
Ours
The forecast the site publishes: the global models blended and then corrected by what the station's own record says about days like the one ahead (the "statistical forecast" on How it was made).
NWS
The National Weather Service's gridpoint forecast for this spot, in whole degrees.
WxSim
The WxSim run on hand at the cut-off; blank when no run had been collected in time.
Avg
The four-model average: the GFS, ECMWF, ICON and GEM global models' own highs and lows for the station's grid point, averaged, with nothing corrected. Ours and the main model are both built on it.
Main
The main model, the candidate on trial (L-038): our own physics column run on the station's readings, corrected by a line fitted on the station's record that also leans on the four-model average. If it beats Ours by May 2027 it becomes the forecast. It issues the day and the night ahead only, so it has no two-days-before column.
Cut-off
Which forecast is graded: the last one each source had out before the period began, the one it had out a day before that, or two days before. Every source is held to the same clock.
Goal and colour
A green cell landed within the goal of the actual; a grey one did not; a blank is a source with nothing out at that cut-off. The top row counts the green cells per column. "Forecast minus actual" shows each cell's miss instead, plus warm, minus cold; hover a cell for the other.

Last 45 days with a finished period. The NWS forecasts whole degrees; a blank cell is a source that had no forecast out at that cut-off (WxSim's runs are not always on hand, and the main model issues the day and the night ahead only, so it has no two-days-before forecast). Ours is the forecast the site publishes. "Within the goal" counts the days each source landed inside the chosen goal at the chosen cut-off. The Scoreboard has the averages and the year-long test.
