In Brief:
Very spring-like weather is here. A ripple in the upper level flow will bring in a chance of rain showers Monday afternoon. We warm up to the 60'sF until a deeper trough passes Thursday/Friday giving us a better chance of rain (and maybe a brief shot of overnight snow). Warmness and niceness settles in right after that. Is winter gone for good!? (Probably not.)
Forecast Discussion:
High pressure dominates Sunday into Monday (Figure 1) with a small storm system moving through southern California. Our next storm (Monday PM) will be kicked off by the upper portion of the trough over Nevada passing our state (Figure 2). A weaker and quick moving low will form east of Denver again and race into Oklahoma/Kansas (Figure 3). The chance of rain showers stretches from 10am - 10pm Monday. With ridging never very far away, we stay warm.
The Longer Range Forecast:
We'll see 60F Tuesday and Wednesday then rain (and a brief snow moment) returns Thursday into Friday (Figure 4). The main trough begins to migrate (more slowly) our way for that rainy period later in the week allowing us to cool a bit too (Figure 5). Snow chances remain up in the northern mountains and foothills over the next 5 days (Figure 6). A dusting is possible down to the western side of town. Rain amounts over the next 5 days are still pretty skimpy sitting between 0.05 and 0.10 inch (Figure 7).
