WHAT HAS CHANGED

  • Again raised sky cover and temperatures further for the next few hours to account for the present clouds/not-as-cold temperatures than the virtually all models are failing to capture. Low confidence on when/if these clouds will thin. It is possible they could stick around all day today.

KEY MESSAGES

1) Dry through Monday with worsening drought conditions.

2) Rain chances return Monday night and remain through the rest of the week, but very low confidence on whether or not there will be notable drought relief.

DISCUSSION

KEY MESSAGE 1...Dry through Monday with worsening drought conditions.

KEY MESSAGE 1 DESCRIPTION... Dry conditions continue, with no precipitation forecast today and Monday. High pressure remains centered to our south, bringing breezy daytime winds across the region on both days. The high pressure will continue to pipe warm air into the region from the southwest. This results in a warming trend today and Monday, with highs in the 50s today, and upper 50s in the north, and low-to-mid 60s Downeast on Monday.

KEY MESSAGE 2...Rain chances return Monday night and remain through the rest of the week, but very low confidence on whether or not there will be notable drought relief.

KEY MESSAGE 2 DESCRIPTION... Low pressure over the Great Lakes moves east, bringing a frontal system that stalls over the northeast Monday into Monday night. Small shortwave on Monday results a chance for light showers in the north beginning Monday night, continuing into Tuesday. Very minimal accumulation with these showers. Tuesday into Tuesday night, backdoor cold front pushes through the north, providing another chance for rain. Anticipating roughly 0.30 inches or less to fall in the north, tapering down to lower accumulations as you move from northern Aroostook county.

Wednesday onwards, confidence in the forecast becomes low. Models are struggling with the placement of a low pressure system in the plains, and whether or not rain will make it into Maine. Some ensembles/models have decent rain, while others have none. Heading toward the weekend, there is a some better confidence in a low pressure system moving into the region from the southeast bringing some moisure, but too early to determine exact timing and location.
