FORECAST:

Unsettled weather for today in a Southwesterly flow aloft. A weak low off the coast should direct most of the available moisture South. A mix of sun and cloud today with the freezing level rising to 1800 meters dropping back down to 1200 meters tonight. Likely more cloud than sun for Thursday into Friday. A deep low offshore will send a potent frontal band for Saturday with a strong impulse around noon. The precipitation will ease up on Sunday morning with drier unsettled weather Sunday afternoon into Monday. A series of frontal bands will push through next week into next weekend. Guesstimates: 0-trace by Friday morning, trace -2 mm by Saturday morning, 20-30 mm by Sunday morning.
