Synopsis
Warmer and drier conditions today. Another round of rain on Tuesday through Wednesday, with slight chances for rain on Wednesday. Dry and warm conditions return towards the latter part of the week and will possibly persist through next weekend.

.SHORT TERM...Monday through Wednesday Night...Warm and dry conditions return today as weak ridging continues to develop across the forecast area. This will result in daytime highs in the mid to upper 70s for inland locations and upper 50s to mid 60s along the coast. However, as the region has experienced, the warm temperatures will not last very long as a broad, upper level trough swings through for Tuesday and Wednesday. This will bring a return of onshore flow, cooler temperatures and light precipitation. 850mb temperatures with the system on Tuesday and Wednesday around 0C will signal cooler than normal daytime highs in the mid 60s for inland locations and mid to upper 50s along the coast. Overnight lows, will also follow a similar pattern and also be slightly below seasonal normals for this time of year. /42

Long Term
Thursday through Sunday...As we transition into the latter part of the week and into next weekend, conditions have the chance to start drying out as the WPC 500 mb clusters show zonal flow to weak ridging to strong ridging. This uncertainty within the models is reflected within the temperature spread seen across the models, which varies from the low 70s to the upper 80s. So, while the trend does point towards warming, just how warm it will get is uncertain. Towards the start of the next weekend, models continue to diverge with some models bringing in a broad trough, which will bring cooler temperatures and precipitation. Other models maintain a broad ridge which would result in warm and dry conditions. So, have leaned into the NBM which has kept a weak ridge over the region. /42

Marine
Calm winds through Monday evening. Tuesday, a trough will enter the waters bringing potential for northwesterly gusts up to 15-20 kt. Seas remain around 5-6 ft through the week. Little to no impacts are expected through midweek. More active weather expected to return Thursday/Friday, with expected gusts up to 20-25 kt suggesting Small Craft Advisory conditions. -JH
