WEATHER CONDITIONS IN THE EAST OF NORWAY

by Knut Jørgen Røed Ødegaard and Unni Fuskeland

In the south of Norway, May 31. is early summer. But the temperatures and the weather may change a lot from one year to another. Even so, the air is in general dryer than later in the summer, and this results in less rain and clouds and some years in longer periods with heat and drought.

Observations done at Jevnaker (145 meter above sea level) may be an example of the conditions in the central part of the southeast of Norway in May/June:

Year	Min. temp	Max. temp	Rain/weather	Comments
2002	4,5	17,5	4,3 mm/showers	Right before a hot periode
2001	6	16	dry spell	Rain the day before (showers)
2000	5	17	insignificant/showers
1999	7	20,5	dry spell	Long periode with nice weather (b. 05.29.)
1998	7,5	22,5	dry spell	Nice periode
1997	7	22	dry spell	Start of a hot periode
1996	8	14,5	9,8 mm/area,showers	Storm in the west, nice before and especially after
1995	11	18	12,4 mm/area,showers	Large flooding in eastern Norway
1994	7	18	dry spell	Storm in the middle of Norway
1993	8,5	18,5	10,9 mm/area,showers
1992	8	29	dry spell	Middle of a long dry periode
1991	5	17	dry spell	End of a long dry periode
1990	7	20	insignificant/area	Rather nice periode
1989	1	7	5,0 mm/area
1988	6,5	22	insignificant/thunder	Unstable period
1987	6	12,5	insignificant/showers	Probably clouds
1986	1	18,5	dry spell	Nice periode
1985	4,5	23	dry spell	Periode with really nice weather
1984	9,5	21	dry spell	Nice periode
1983	5	21	insignificant/showers
1982	-	Over 20	dry spell	Nice periode

The minimum temperatures will in general be higher in Oslo and in areas near the coast, and the maximum temperatures somewhat lower the farther north. When rain comes from a precipitation area, it indicates a long term, continuous cover of clouds.

A great deal of the rain comes as showers in the afternoon. These clouds are caused due to heating of the Sun during the day. In general the same heating causes a decreased cover of clouds in the afternoons. Since the eclipse happens early in the morning, these kinds of clouds will not have been created.
