Exceptionally warm weather through Monday becomes a chance of showers Tuesday then more seasonable temperatures.
We received less than 1/10th of an inch in Longmont, but any moisture is good (Figure 2 update). We warm up except for a chill on Friday (a mostly dry cold front). Heads up, though... middle next week on through next weekend looks chilly and wet day after day. More on that later!
End Wednesday update.
The front arrives this evening, but rain is delayed. It looks like about a quarter inch of rain will fall between mainly noon and 6pm Tuesday (Figure 1 update). The GFS (Figure 2 update) is more bullish about rainfall and gives us 1/2 to 3/4th inch of rain (Note: that IS the 10 day total, the next 48 hours gives us less than 1/10th inch from the GFS). That would be nice! Enjoy Spring showers!
End Monday Update.
A giant ridge over the western U.S. (Figure 1) is making much of the nation think thoughts of summer (Figure 2). Temperature anomalies in the second figure are 20-30 degrees above normal from Arizona up into the upper Midwest.
The Longer Range Forecast:
The ripple (trough) on the western side of the ridge is slowly approaching Colorado (Figure 1). That will give us about 1/10th of an inch of rain on Tuesday (Figure 3). The ridge breaks down a bit after this and we remain in the upper 60s and lower 70s for much of the rest of the week, closer to normal. Enjoy and Happy Easter!
