KEY MESSAGES

- Occasional chances for showers can be expected beginning Sunday night with the best chances Monday night and Tuesday with less than a quarter inch within a 12 hour period expected.

DISCUSSION

WEATHER PATTERN OVERVIEW:

Upper trough over the western states has been weakening allowing the rainshowers over the eastern zones to move off to the northeast of the CWA. Temperatures are again cooler than normal with expected highs in the mid 60s to low 70s, about 10 to 15 degrees below normal.

Models are progging that the upper ridge to our southeast will rebound a bit this weekend. But with the abundant low-level moisture around, any of the sun's energy will initially go into evaporation. Thus highs on Saturday will once again be below normal. Also, fog doesn/t look to be a major concern for Saturday morning as abundant clouds tonight should keep radiational cooling from occurring. Later shifts may have more info on this, so some patchy fog is possible come Saturday morning.

Additional warming is expected Sunday with more sunshine. Look for highs in the mid 70s to low 80s with light winds. Similar conditions are expected Monday. Clouds will increase late in the day with the next disturbance moving in.

Models then have showers and cooler conditions for Tuesday that linger into Wednesday. Rainfall amounts should be less than a quarter inch in a 24 hour period. Could be enough to cause travel issues for unpaved roadways but also keep the fire danger low.

Said disturbance moves out Wednesday with a return to warmer and drier conditions for the end of the week.

FORECAST CONFIDENCE & DEVIATIONS: Overall, NBM held the line through much of the forecast period. Confidence is increasing on mainly dry conditions this weekend with a warmup through Monday. TFJ
